Diamondback Energy, Inc. vs OCCIDENTAL PETROLEUM CORPORATION, two Oil & Gas stocks. A side-by-side on valuation, growth, margins, returns, and what each price is betting.
The reported margins mislead for Diamondback, whose Endeavor-acquisition costs crush its trailing 1.87% net margin and 0.67% return on equity into meaninglessness, so the honest read is its 16.2% free-cash yield against Occidental's 6.7% and its Permian scale beneath the noise. Occidental nets a clean 22.4% of revenue on oil-plus-chemicals, earns 12.1% on equity, and carries 0.39 turns of debt against Diamondback's 0.33. Both pay near-2% dividends. The pair prices two large US oil producers, Diamondback the Permian's biggest pure play post-Endeavor, Occidental the diversified operator with chemicals and Buffett's preferred overhang; read Diamondback on cash flow, Occidental on its clean income statement, and both as cheap oil exposures.
