OXY OCCIDENTAL PETROLEUM CORP /DE/ Insider Trading

Director William R Klesse purchases 5,000 OXY shares at $38.98; stock down 14.2% in 90 days, now $40.63

Director William R Klesse purchased 5,000 shares at $38.98 on 2025-12-16, increasing his holdings to 218,913 shares. The purchase occurred as Occidental Petroleum's stock has declined 14.2% over the prior 90 days and trades 22.9% below its 52-week high of $52.70. The company is experiencing headwinds: annual revenue growth contracted 5.4% year-over-year, though the latest quarter generated $6.6B in revenue with $842.0M in net income. The transaction represents a small addition (2.3% increase to his pre-transaction position), occurring against a backdrop of sector softness rather than a dramatic repricing opportunity.

Berkshire Hathaway buys 763,017 OXY shares for $35.7M; 19-stock track record shows +4.1% avg 30d return on prior buys

Berkshire Hathaway, a 10% owner of Occidental Petroleum, purchased 763,017 shares at $46.82 on 2025-02-07, bringing its stake to 264,941,431 shares (264.94M shares). This transaction represents a deliberate addition by one of the company's largest shareholders at a price 3.8% below the current market price of $48.61 and significantly below the 52-week high of $69.26. Berkshire's cross-ticker track record of 19 prior open-market buys averaging +4.1% 30-day returns establishes a documented pattern of acquisition timing that has been profitable in the near term across its broader portfolio activity. The purchase occurs against a backdrop of OXY's material FY revenue decline of -22.9% and a depressed valuation (P/E: 10.57), combining a substantial shareholder action with measurable historical precedent, warranting investor attention to the signal and underlying business conditions driving the acquisition.

Berkshire Hathaway purchases 8,896,890 shares of OXY for $409,153,147.93 across 5 transactions; stake now 264,178,414 shares.

Berkshire Hathaway as a 10% owner executed 5 separate purchases of Occidental Petroleum totaling 8,896,890 shares for $409,153,147.93 at a blended average price of $45.99 between December 17–19, 2024. This increased its holdings by 3.5% to 264,178,414 shares. The timing coincides with OXY trading at -34.5% from its 52-week high of $69.26 and -10.2% down over the prior 30 days, reflecting material downward price momentum. The company's fundamentals show quarterly net income of $1,140,000,000.00 against a P/E of 9.86, though annual revenue declined -22.9% year-over-year, indicating operational headwinds. Berkshire's cross-ticker open-market purchase history averages -1.4% return within 30 days, suggesting prior acquisitions have not captured immediate upside; this multi-tranche purchase pattern occurs in a depressed valuation environment for the target but carries no certainty of near-term recovery.
