What to look at in Energy companies
- FCF yield (>8%) — Cash generated / market cap. In energy FCF beats EPS.
- ROIC 5y avg (>=10%) — Include good and bad years to filter the truly disciplined.
- Positive FCF in 8 of last 10y (>=8/10) — Disciplined names (XOM, CVX, EOG) survive 2014-16 and 2020 crashes.
- Dividend coverage (FCF / div) (>=1.2x) — Dividend covered by FCF, not borrowed. <1x = likely cut.
- Net Debt / EBITDA (<2x at peak) — Look at it with trough EBITDA, not the peak.
- Capex / Revenue (10-20% healthy) — Energy needs aggressive reinvestment to maintain reserves.
