Warren Buffett’s Berkshire Hathaway announced Thursday it reached a deal to buy Occidental Petroleum’s petrochemical unit, OxyChem, for $9.7 billion in cash.
The deal marks Berkshire’s largest since 2022, when it paid $11.6 billion for insurer Alleghany. It also comes at a time in which the conglomerate is sitting on $344 billion in cash, a record for the company.
Berkshire is already a major investor in Occidental, holding a 28.2% stake as of the end of June. Buffett — who is 95 and stepping down as CEO at the end of the year — has said he wouldn’t take complete control of the oil company.
Buffett began buying Occidental stock in the open market in 2022, taking advantage of heightened market volatility to scoop shares at cheaper levels.
OxyChem manufactures water treatment, healthcare and other commercial chemicals. Occidental said it will use $6.5 billion of the proceeds to pay down debt.
“We look forward to welcoming OxyChem as an operating subsidiary within Berkshire,” said Greg Abel, Vice Chairman of Non-Insurance Operations at Berkshire, in a press release. Abel, who will replace Buffett as CEO of Berkshire in 2026, added that Occidental CEO Vicki Hollub is showing her “commitment to Occidental’s long-term financial stability, as demonstrated by their plan to use proceeds to reinforce the company’s balance sheet.”
Both companies expect the deal to close in the fourth quarter. The Wall Street Journal first reported on the transaction earlier this week.
