Occidental Petroleum: A Deep Dive Through Buffett's Lens

Occidental Petroleum (NYSE: OXY) is the most layered of Berkshire Hathaway's energy bets, and the one that best shows Buffett thinking in instruments rather than in slogans. The relationship began in April 2019, when Occidental was racing to buy Anadarko Petroleum and needed to beat Chevron's existing bid. Berkshire committed $10 billion of preferred stock — paying an 8% dividend, redeemable at a premium — plus warrants to buy 80 million common shares at $62.50 (later adjusted to about $59.62). That preferred alone throws off roughly $800 million a year in cash.

Then, in late February 2022, Buffett started buying the common stock in size — about $7 billion for roughly 14% of the company in just three weeks — and kept adding. Berkshire now owns well over a quarter of Occidental's shares and has regulatory permission to go as high as 50%. The position is a stack: protected income on top, long-dated optionality in the middle, and a large common stake at the bottom.

The Moat: Permian Acreage and Low-Cost Oil

Occidental's operating economic moat is its resource base. The company is one of the largest acreage holders in the Permian Basin, the most prolific oil region in the United States, with low lifting costs and long-lived wells. That means it can earn acceptable returns at prices where higher-cost producers bleed. Like Chevron, it benefits from integration and from a chemicals business (OxyChem) that smooths the cycle, and it has pushed early into carbon capture and direct-air-capture — a longer-shot "green option" on top of the core oil franchise.

Buffett has been explicit that he does not know where oil will trade next month or next year. What he trusts is the asset and the operator. In the 2023 shareholder letter he wrote: "No one knows what oil prices will do over the next month, year, or decade. But Vicki does know how to separate oil from rock, and that's an uncommon talent, valuable to her shareholders and to her country." At the 2023 meeting he added that "Hollub is an extraordinary manager at Occidental. We love having Vicki run it" — and confirmed Berkshire would not make a bid to control the company. For a value investor, that is a rare thing: a commodity business where the boss is praised for capital discipline and debt paydown rather than for empire.

Capital Allocation: A Stacked, Patient Structure

The 2019 deal is a capital allocation template. The preferred is defensive — senior, income-producing, redeemable at a premium — while the warrants are offensive, giving Berkshire the right to convert that position into common at a fixed strike. The later common purchases were made mostly when the stock was below $60, a price Buffett has suggested he prefers. The result is a position that earns protected cash in the meantime and participates in the upside if oil and the Permian deliver.

For an owner, the relevant measure is owner earnings: free cash flow after the heavy capital spending needed to hold production flat. Occidental's management has pledged a sensible order — pay down debt, then buy back stock, then consider raising the dividend — which is exactly the hierarchy a patient holder wants to see.

The preferred piece deserves its own note. Berkshire's $10 billion of Occidental preferred pays 8% annually — roughly $800 million of cash flow to Berkshire every year, whether the stock rises or falls. The warrants, exercisable for years after the preferred is redeemed, let Berkshire convert that position into common at a fixed strike, so the same capital first earns protected income and then can convert into upside. This is the heart of Buffett's energy playbook: get paid to wait, and keep an option on the recovery. A private investor cannot replicate the terms, but the principle transfers — structure matters, and seniority protects you when the cycle turns.

Valuation and Margin of Safety

With a leveraged oil producer, intrinsic value is hostage to the oil deck and to the balance sheet. The margin of safety for Berkshire was built in two ways: the 8% preferred sits ahead of common shareholders, and the common was accumulated at prices well below the warrant strike. For a new buyer, the safety comes from assuming a lower, more durable oil price and from a management that keeps de-levering; it does not come from hoping crude spikes.

ValueOS does not forecast commodities. It asks whether the business survives a long stretch of weak prices and still rewards patience. On that test, Occidental's low-cost Permian base and its debt paydown matter more than any single quarter's realization.

Risks to Watch

• Leverage. Even after paydown, the balance sheet carries acquisition-era debt that amplifies downside in a price slump.
• Commodity price. A sustained low-oil environment compresses cash flow and pressures the equity.
• High beta. Occidental moves far more than an integrated major like Chevron when sentiment shifts.
• Execution. Integrating Anadarko and scaling carbon-capture ventures both carry operational risk.

What Value Investors Should Take Away

Occidental is a study in staying inside your circle of competence: Buffett admits he cannot price oil, so he structures the investment to be paid while he waits and to benefit if his long-term view proves right. It is patient compounding wrapped around a real asset and a manager he respects, held through Berkshire Hathaway with the patience only permanent capital allows. The lesson is not "oil always goes up." It is that you can own a cyclical business safely if you stack the odds — protected income first, sensible price second, trusted operator third — and never confuse a cheap option on oil with a forecast you cannot make.
