Occidental (OXY): The Permian operator Buffett blessed.
The read · Machine
Permian-weighted US producer with a meaningful OxyChem chemicals segment and a developing carbon-capture business at Stratos. The 2024 CrownRock acquisition added Midland Basin acreage. Berkshire Hathaway holds a 28%-plus stake (approx.). Vicki Hollub has been CEO since 2016 and led the Anadarko acquisition and post-acquisition recovery.

The Trough Test
The note · Principal
The note
Occidental is the Permian producer with three distinguishing pieces of optionality. The Permian itself, which the August 2024 CrownRock acquisition extended into the Midland Basin. The OxyChem chemicals segment, which prints counter-cyclical cash when the upstream is weak. And the carbon-capture business at Stratos, whose commercial pathway is the part the market keeps over-modelling or under-modelling depending on the week.
The business, in one paragraph
Total production sits around 1.4 MMboe/d post-CrownRock, with the Permian contributing more than half. The Anadarko legacy includes meaningful Gulf of Mexico and international positions. OxyChem produces chlorovinyls and is a top-three North American producer in that category; the chemicals cycle does not move in step with the oil cycle, which is the structural hedge. The Stratos direct-air-capture facility is the proof-of-concept for the carbon-capture business; commercial scale and the carbon-offset pricing pathway are being built.
What FY 2025 actually said
The CrownRock integration progressed broadly on schedule. Per-well productivity in the new Midland Basin acreage was within the original case. The net debt walk continued toward the US$15B near-term target. The OxyChem segment contributed meaningfully through a chemicals tape that was uneven. Stratos began commercial operations and the first batch of carbon offsets was negotiated. The dividend continued at the modest level set post-2020.
Two things we are reading carefully
1. The CrownRock integration
CrownRock was a US$12B-class acquisition that extended Occidental's Midland Basin position at a price that requires the per-well productivity to hold. The early data is encouraging; the 2026 quarterly data is the part that will settle the question. We track type curves, completion intensity, and the unit cost at the integrated assets versus the legacy Occidental acreage.
2. Carbon capture
Stratos is the most ambitious carbon-capture commercial program in the industry. The optionality is real; the commercial pathway is not. We track the offset-pricing negotiations, the next facility build pace, and any policy change that affects the underlying economics. The Pillar III thesis improves with credible commercial proof; the Pillar I thesis works without it.
What we are watching into FY 2026
- Permian per-well productivity at the CrownRock acreage.
- OxyChem contribution through the chemicals cycle.
- Net debt walk toward US$15B.
- Stratos commercial pathway and second-facility timing.
The Berkshire stake is not the thesis. The integrated business is the thesis. The Berkshire stake is the receipt.
Checklist scorecard
Ten questions, three pillars. Status icons reflect the principal's read on this name; absent a green dot, fall back to the question's standard note. See the full Checklist for the framework.
Pillar I
The business
Does it generate free cash flow through the full cycle, or only the top half of it?
Not yet
FCF through full cycle is positive on average; 2015–2016 stress was real and the dividend was cut.
Do the unit economics still work at the worst price of the last decade?
Pass
Permian unit economics at US$50 WTI are sound. OxyChem is a counter-cyclical contributor that smooths the worst quarter.
What does the balance sheet look like at trough pricing: net debt, covenants, maturity ladder?
Not yet
Net debt remains elevated post-CrownRock; the walk to the US$15B target is the near-term work.
When they reinvest a dollar (capex, M&A, or buyback), what actually comes back?
Not yet
The Anadarko acquisition was the defining capital decision; the verdict has improved since but cost the dividend in 2020.
Pillar II
The people
How much of the operator's own net worth, bought and not granted, sits in this name?
Not yet
Insider ownership is modest at the executive level. The Berkshire stake is the more important capital signal.
What did management actually do in 2015 and 2020: issue, buy back, or sit still?
Not yet
2015: dividend cut. 2020: dividend cut to a penny. Both were rational; neither was clean.
Is compensation tied to per-share value, or to production, revenue, and size?
Not yet
Compensation is partially per-share-aligned. The legacy Anadarko-era plan was production-sized.
Who succeeds the operator, and is that person already visible on the page?
Not yet
Succession is not visible. Hollub has been CEO for a decade. The bench question is real.
Pillar III
The cycle
Where are we on the cost curve that matters: the real one, not the one in the pitch deck?
Pass
Permian acreage post-CrownRock sits in the first quartile of US shale economics.
What does a “normal” year look like a decade from now, and does this business still work at that price?
Pass
Underwriting at mid-cycle WTI of US$65–75, Occidental produces meaningful free cash. OxyChem is the structural hedge.

Pillar I. The business. Occidental is the Permian-weighted US producer with a meaningful OxyChem segment that prints counter-cyclical cash. The 2019 Anadarko acquisition was the defining capital decision of the prior cycle and the 2024 CrownRock acquisition extended the Midland Basin position. Per-well productivity in the new acreage is the part FY 2026 will test. The carbon-capture business at Stratos is a longer-cycle option whose commercial pathway is being negotiated rather than proven.
Pillar II. The people. Vicki Hollub has been CEO since 2016 and is the principal capital allocator. The Anadarko decision was bold and costly in 2020; the post-2020 recovery has been impressive. The Berkshire 28%-plus stake is a meaningful Pillar II signal that we read as a quality vote on the capital culture. Compensation is incrementally per-share-aligned. Succession is the open question.
Pillar III. The cycle. Permian per-well productivity has continued to improve through the cycle. OxyChem is a structurally counter-cyclical contributor. Carbon capture is a long-cycle option whose commercial economics are still being built. Underwriting at mid-cycle US$65–75 WTI, Occidental produces meaningful free cash. The decade-out question is what role Permian shale plays as the US gas-and-LNG complex grows, and how Occidental positions for the answer.
