The Financial Times reported that Berkshire Hathaway is in final talks to purchase the petrochemical division of Occidental Petroleum, its largest deal in three years. The divestiture would reduce Occidental’s $24 billion debt load. Buffett is the largest shareholder in Occidental today, owning 26.9% of the company’s outstanding shares.
The OxyChem division reportedly generated nearly $5 billion in revenue last year and market cap of Occidental Petroleum is estimated to be $46.5 billion as of Tuesday’s close of market. An announcement of a finalized deal could come as early as this week.
Merger of the two companies will create the world’s largest regulated electric utility business.
