Buffett's $10 Billion Check, How Berkshire's White-Knight Financing Pulled Anadarko from Chevron to Occidental

The defining theme of US shale in 2019 was Permian Basin consolidation. Spanning West Texas and southeastern New Mexico, the Permian accounts for roughly 30% of US crude production, and the 2015-2018 shale revolution drove drilling-cost compression that attracted every major to the basin. By April 2019, ExxonMobil and Chevron were leading the integrated-major push, with the independent E&Ps either being absorbed or scaling up themselves. Anadarko sat among the top five US independents with an attractive triangle of Permian + Gulf of Mexico deepwater + Algeria and Mozambique LNG. Occidental was the most Permian-concentrated of the integrated independents, a Permian pure play for whom Anadarko would double Permian production and grow shale reserves ~70%.

OXY-Anadarko is one of the rare US energy deals where white-knight financing, Permian consolidation, and asymmetric size, David vs. Goliath converged in a single transaction. The 2023-2024 mega-deals, ExxonMobil-Pioneer ($65B) and Chevron-Hess ($53B), have since cemented the view that the 2019 OXY-Anadarko transaction was the opening move of the Permian consolidation cycle.

Anadarko Petroleum Corporation was founded in 1959, headquartered in The Woodlands, Texas, and counted among the top five US independent exploration-and-production companies at the time of the transaction. As of 2019, average daily production ran at roughly 700,000 BOE/day with reserves of ~1.5 billion BOE. Three portfolio pillars: ① Permian Basin shale (Delaware and Midland sub-basins), ② Gulf of Mexico deepwater production, and ③ Algerian and Mozambique LNG projects, with the Mozambique LNG asset being one of the most-watched global gas projects of the late 2010s. Occidental sold the African package, Mozambique, Algeria, Ghana, South Africa, to Total SA at deal close, leaving the post-deal entity focused on US Permian production.

The transaction is best read as three interlocking structures: ① OXY acquires Anadarko at $76/share, a mix of cash and OXY stock, ② OXY funds the cash component of the acquisition with Berkshire's $10B perpetual preferred + 80M warrants, and ③ OXY simultaneously sells Anadarko's African assets to Total SA for ~$8.8B at deal close to partially offset leverage. The Berkshire preferred carries an 8% cash dividend (9% PIK if unpaid), is callable by OXY only after April 2029, and ranks junior to debt and senior to common. The warrants entitle Berkshire to purchase 80M OXY common at $62.50, exercisable at any time during the life of the preferred. No acquisition financing syndicate, no LBO debt, the deal funded on Berkshire's balance sheet equity plus OXY's own credit.

The bidding-war structure created a four-corner advisor map: Anadarko (target) was advised by Evercore and Wachtell; OXY (challenger) by BofA and Citi with Cravath; Chevron (incumbent) by Credit Suisse and Goldman with Paul Weiss. Berkshire, characteristically, used no external advisors, Warren Buffett ran the entire commitment in-house.

Three valuation lenses define this transaction: ① the Anadarko purchase EV/EBITDA, headline price-to-asset metric, ② mark-to-market of the Berkshire preferred, credit and yield, and ③ option value of the warrants. Chevron's initial $65 bid valued Anadarko at roughly 7.5x EV/EBITDA, in line with peer transactions. OXY's $76 counter at roughly 9.0x EV/EBITDA implicitly pre-paid the Permian synergy in cash. The Berkshire preferred, at an 8% cash coupon on OXY (BBB+ at issuance), priced at roughly 200-250 bp wide of OXY's secondary credit spread. The warrants, struck at $62.50 against an OXY spot of ~$58 at issuance, started ~8% out-of-the-money; the 2022-2024 oil-price rally pushed OXY into the $60-80 range, making the warrants meaningfully in-the-money for extended periods.

Note: EV/EBITDA estimates use Anadarko's FY2018 EBITDA of ~$6.8B. Market data points may vary by source and timing.

Seven years after closing, the deal has cycled through three inflection points and lands in a very different place than 2019 critics expected. ① 2020 COVID oil-price collapse: OXY fell from $40s to ~$10, and debt covenants forced OXY to pay part of the Berkshire preferred dividend in OXY common stock (PIK), peak winner's curse narrative. ② 2022-2023 Russia-Ukraine energy spike: OXY shares recovered into $70-80, warrants moved firmly in-the-money. ③ 2024-2025 Buffett accumulation: open-market purchases brought Berkshire's OXY common stake to ~28% (~250M shares), which combined with the preferred and warrants positions Berkshire as the effective anchor shareholder. Carl Icahn gradually exited his activist position during the 2022 recovery. OXY itself paid down ~$20B+ of debt between 2020 and 2023, normalizing net debt / EBITDA from ~5x at close to ~1.5x. In 2025, OXY redeemed ~$4B of the Berkshire preferred at par. Vicki Hollub, throughout, has been consistent: "The hardest five years, but we were right."
