As of Q4'25, Occidental Petroleum (OXY) reported revenue of USD 2.06B, representing a sharp decline from previous quarters. Year-over-year revenue growth for this period was -69.88%, indicating a significant contraction compared to the same quarter last year. Over the period from Q1'23 to Q4'25, OXY's revenue exhibited considerable volatility, with figures generally fluctuating between USD 6B and USD 7.5B before the steep drop in Q4'25. While there were intermittent quarters of modest growth—such as Q2'24 (2.20% YoY) and Q1'25 (13.86% YoY)—the overall trend was downward, culminating in a dramatic revenue decrease at the end of 2025. This suggests mounting challenges for the company, particularly in the latter part of the observed timeframe.
