Occidental Petroleum Corporation outlined key considerations expected to affect its fourth quarter 2025 results, noting that the disclosure is preliminary and not a full earnings estimate. The company highlighted the completed sale of Occidental Chemical Corporation (OxyChem) on January 2, 2026, which will result in OxyChem being reported as discontinued operations starting with the 2025 Form 10-K. For the quarter, Occidental expects an adjusted effective tax rate of 35%–37% for continuing operations and 24%–26% for discontinued operations, with average diluted shares outstanding of 1.0029 billion.

Occidental also provided details on commodity realizations for the quarter ended December 31, 2025. Average realized worldwide oil prices were $58.99 per barrel, compared with average index prices of $59.14 for WTI and $63.09 for Brent. Worldwide natural gas liquids averaged $16.66 per barrel, while natural gas realizations averaged $1.29 per Mcf, reflecting about 31% of average NYMEX gas prices. The company emphasized that actual results may differ materially from current expectations due to factors such as commodity price volatility, geopolitical risks, regulatory changes and broader economic conditions.
