MPLX

MPLX is exactly what a midstream MLP should look like: five straight years of higher revenue ($8.02B→$9.73B since FY2021) and net income ($3.11B→$4.95B), with FY2025 net income up 13.7% and operating income up 12.4% — earnings growing roughly twice as fast as the 5.8% top line, a sign of fee-based operating leverage. Margins are extraordinary and stable for the model (61.1% operating, 50.9% net), and the business throws off cash: $5.91B operating cash flow against $1.81B capex leaves ~$4.1B of free cash, comfortably funding the $400M of buybacks (+22.7%) while cash on hand grew 40.7% to $2.14B. On valuation this is the crux — at a $57.7B cap on $4.95B of net income the stock trades near 11.7x earnings (P/S 5.9), an undemanding multiple for an asset with this consistency and cash generation.

The balance sheet carries the leverage typical of the structure and is the main thing to respect: liabilities/equity sits at 3.08x and total liabilities rose 21.2% YoY to $28.5B, outpacing both revenue and assets (+14.6%). The headline 53.5% ROE is therefore flattered by leverage rather than a sign of unusual asset returns. Note also a data quirk — the reported stockholders' equity line is labeled FY2015 with a nonsensical +1898.7% change, so equity-based ratios should be read with caution (assets minus liabilities implies ~$14.5B of total equity including noncontrolling/preferred interests).
