In Q4'25, Occidental Petroleum's (OXY) operating cash flow stood at $2.63B USD, reflecting a moderate decline from the Q3'25 figure of $2.79B USD but remaining above the yearly low of $2.15B USD in Q1'25. Free cash flow, meanwhile, surged to $1.88B USD in Q4'25, marking a significant rebound from $0.94B USD in Q3'25 and approaching the peak of $1.98B USD seen in Q3'24. Over the period from Q1'23 to Q4'25, operating cash flow exhibited steady growth in 2023, peaking at $3.24B USD in Q4'23, before fluctuating with notable dips to $2.01B USD in Q1'24 and $2.15B USD in Q1'25, followed by a partial recovery to $3.35B USD in Q4'24. Free cash flow followed a similar volatile pattern, rising from $1.39B USD in Q1'23 to $1.77B USD in Q4'23, then dropping sharply to $0.28B USD in Q1'24 amid higher capital expenditures, with strong rebounds in Q3'24 ($1.98B USD) and Q4'25 highlighting resilience in cash generation despite quarterly inconsistencies. Overall, both metrics underscore OXY's ability to maintain positive cash flows, though subject to oil market volatility and investment cycles.
