This significant acquisition by Warren Buffett's Berkshire Hathaway of OxyChem, Occidental Petroleum's chemicals division, for $9.7 billion represents a strategic move that aligns with Buffett's long-standing investment philosophy. It marks a substantial investment in a traditional industry, demonstrating his confidence in sectors with stable demand and strong underlying fundamentals. The deal is poised to deliver mutual benefits: Occidental Petroleum gains the ability to significantly reduce its debt, thereby strengthening its financial position, while Berkshire Hathaway integrates a profitable, essential business into its diverse portfolio, reinforcing its presence in vital industrial sectors.
Berkshire Hathaway's Major Chemical Industry Investment
At 95, investment icon Warren Buffett, leading Berkshire Hathaway, has executed a substantial acquisition, securing OxyChem, the chemical segment of Occidental Petroleum, for $9.7 billion in an all-cash transaction. This marks his most considerable deal in several years. The purchase involves a well-established entity known for producing crucial industrial chemicals, such as chlorine, vital for applications ranging from water purification to construction materials and healthcare products. This strategic move leverages Berkshire's substantial cash reserves, transforming idle capital into a revenue-generating asset and aligning with Buffett's disciplined approach to investment.
This latest acquisition, finalized on October 2, 2025, reflects a calculated decision by Buffett to deepen Berkshire Hathaway's involvement in a business sector already familiar to him, given Berkshire’s existing 27% stake in Occidental. Beyond capital deployment, the deal creates strong synergistic opportunities. Berkshire Hathaway's existing energy infrastructure, including significant holdings in oil and gas and ownership of pipelines through Berkshire Energy, will complement OxyChem’s operations in petrochemicals. The stability of demand for OxyChem’s products—essential for water treatment, pharmaceuticals, and housing—further underscores the logical appeal of this acquisition. This methodical investment is a clear demonstration of Buffett’s preference for fundamental industries over volatile, high-growth sectors, continuing his tradition of seeking value in overlooked areas.
Market Reception and Strategic Rationale of the Acquisition
Following the announcement, Occidental Petroleum’s stock experienced a 7% decline, attributed by some to the expected loss of future earnings from the divested chemical business. However, industry analysts largely praised the transaction. Doug Leggate of Wolfe Research, for instance, described the deal as a “stroke of genius,” highlighting the dual advantage: Berkshire Hathaway acquires a robust, independent business, while Occidental Petroleum significantly pares down its debt, improving its financial health. This financial maneuver was seen as a prudent capital allocation, enhancing Occidental’s balance sheet despite the immediate dip in share price. Meanwhile, Berkshire Hathaway's shares showed minimal movement, reflecting the sheer scale of its operations where a $9.7 billion deal has a relatively minor impact.
Buffett’s investment strategy has consistently emphasized businesses within his “circle of competence,” steering clear of speculative ventures and focusing instead on sectors like insurance, utilities, and industrial goods. This acquisition of OxyChem, a petrochemical enterprise, is a classic Buffett move—a firm commitment to an “old-economy” industry that boasts steady demand and a clear operational model. By opting for petrochemicals, Buffett reiterates his commitment to tangible assets and essential services, diverging from contemporary trends towards technology. This strategic choice allows him to deploy capital into a well-understood, reliable income stream, affirming his unique ability, even at 95, to identify and capitalize on enduring market opportunities.
