As of Q4'25, XOM's EV/Sales ratio stands at 0.71, marking a substantial decline from previous quarters. This latest data point represents a significant drop compared to Q3'25, when the ratio was 5.95. Over the period from Q1'23 to Q4'25, the EV/Sales ratio for XOM generally remained stable within the 4.7 to 5.9 range, with minor fluctuations and a modest upward trend peaking at 5.96 in Q3'24 and Q3'25. However, the sharp decrease to 0.71 in Q4'25 indicates a notable inflection point, suggesting a dramatic change in either enterprise value, sales, or both, and warrants further investigation into the underlying drivers of this sudden shift.
