Marathon Petroleum Corporation MPC

our econometric model implies MPC’s 5% revenue growth is driven by efficiency-driven margin expansion and channel optimization rather than volume, underscored by an SG&A ROI of $23.14 per $1 and a positive revenue elasticity to SG&A spend. The holdout error of about 8% (35.2B predicted vs 32.6B actual) signals forecasts are reasonably reliable but can overshoot in volatile refining margins; the overall MAPE of 10.5% remains within a practical range for a cyclical business. The growth rate’s sensitivity to margins and throughput means MPC’s upside depends on refining cracks and utilization; shifts in crude differentials or demand, plus capex intensity and capacity additions by peers, could re-rate cash flow and earnings.
