IMPERIAL OIL LIMITED vs SUNOCO LP, two Oil & Gas Refining stocks. A side-by-side on valuation, growth, margins, returns, and what each price is betting.
The margin comparison crosses business models: Imperial Oil nets 6.2% of revenue as an integrated producer-refiner, Sunoco 3.1% as a fuel-distribution MLP running a toll on terminals and pipelines. Imperial earns 12.8% on equity and 6.4% on assets, real integrated returns; Sunoco's structure yields no clean equity figure and pays through distributions, its 28.5% free-cash figure a pass-through mechanic. Imperial pays a 1.9% dividend at 26.1 times earnings; Sunoco has no usable P/E. Imperial carries 0.15 turns of debt. The pair prices integrated oil against fuel logistics, a producer against a distributor; they touch only at the downstream fuel border, and Imperial's returns are the kind Sunoco's model structurally cannot generate.
