The sector that refuses to collapse
When we last looked at energy in early April, the sector had 10 A-grades and five failures. A month later: 11 A-grades, still five failures. The grade distribution barely moved, but the individual names tell a different story.
The median FCF margin sits at 9.0%. That's respectable for a capital-intensive sector dealing with commodity price swings. What stands out is the bifurcation: natural gas producers printing 20%+ margins while refiners scrape by at 2-4%. This isn't a sector. It's two separate businesses wearing the same label.
Natural gas runs the show
EQT leads with a 33.2% FCF margin and an improving trend. Coterra follows at 20.6%, also improving. APA hits 19.9% but shows a declining trend despite the A-grade. Occidental manages 19.0% while improving. Kinder Morgan rounds out the top five at 17.1%, trending up.
The natural gas thesis is simple: domestic demand stayed strong, export infrastructure kept expanding, and these companies didn't blow their cash on empire-building. EQT's margin is higher than most tech companies. That's not a typo. A natural gas producer is generating more cash per dollar of revenue than the average software business.
But here's the catch with APA. A 19.9% margin earns the A-grade, but the declining trend suggests something shifted in recent quarters. Could be production costs creeping up, could be hedge positions rolling off, could be capital spending ticking higher. The grade reflects current health. The trend tells you where it's headed.
The integrated majors hold steady
Chevron grades out at an A with a 9.0% margin and improving trend. ExxonMobil also gets an A at 7.3%, though the trend is stable rather than improving. ConocoPhillips hits 12.3% with an upward trajectory.
These companies benefit from diversification. When upstream gets squeezed, downstream picks up some slack. When oil prices spike, refining margins compress but production profits jump. The model works, even if the FCF margins don't match the pure-play gas producers.
Exxon's stable trend at 7.3% is interesting. It's not growing, but it's not shrinking either. The business is generating steady cash in an unstable commodity environment. That consistency matters more than most investors realize.
Refiners are a wreck
Phillips 66 prints a 2.1% margin with a declining trend. Grade: F. Marathon Petroleum manages 3.6% while improving, barely scraping a C. Valero hits 4.1% with an improving trend but still grades B because the margin is thin. Targa Resources sits at 3.0%, declining, graded F.
The refining business model is broken at current margins. These companies convert crude into products, but they don't control input costs or output prices. When crack spreads compress, there's nowhere to hide. A 2-3% FCF margin leaves zero room for error.
Marathon's improving trend at 3.6% suggests recent quarters got better, but the absolute level is still concerning. One bad quarter and that margin goes negative. Valero's 4.1% with an improving trend earned the B-grade, but it's still a capital-intensive business generating barely enough cash to cover maintenance spending.
The pipeline paradox
ONEOK grades F at 7.3% with a declining trend. Williams Companies gets an F at 6.7%, also declining. These margins aren't terrible in absolute terms. The F-grades come from balance sheet issues or consistency problems, not just the margin level.
Pipelines should be cash machines. Fixed infrastructure, contracted revenue, predictable volumes. The fact that two major pipeline operators are declining and graded F suggests either leverage is too high, growth spending is eating cash, or the contracts aren't as stable as the pitch deck claimed.
Kinder Morgan, by contrast, hits 17.1% with an improving trend and an A-grade. Same business model, completely different execution.
Diamondback's negative margin
Diamondback Energy sits at negative 4.7% FCF margin. The trend is improving, which means recent quarters were less bad than earlier ones, but you can't grade a negative margin anything other than F.
This is a Permian pure-play that should be printing cash. A negative margin means either spending massively outpaced cash generation or the company hit accounting headwinds. The improving trend suggests they're fixing it, but you don't get credit for improvement when the starting point is underwater.
What the trends reveal
Ten companies show improving trends. Three are stable. Eight are declining. That's a better distribution than most sectors show. Half the sector is getting healthier in real time.
The improving names aren't random. EQT, Coterra, Occidental, Kinder Morgan, ConocoPhillips, Chevron: these are companies that either caught the natural gas wave or managed their capital discipline better than peers. The declining names cluster in refining and pipelines, suggesting structural headwinds rather than company-specific issues.
The sector's average debt-to-FCF ratio is 8.0x. That's elevated but not catastrophic. Energy companies carry debt because the assets are long-lived and predictable. The question is whether FCF generation can grow faster than the debt load. At current trends, the answer is mixed.
Where energy stands
This sector has 11 A-grades out of 21 analyzed companies. That's a 52% hit rate, better than consumer discretionary, better than utilities, worse than technology. The median margin is strong enough to support the business models. The trend breakdown tilts positive.
But the sector is really two sectors. Natural gas producers and integrated majors are healthy. Refiners and some pipeline operators are struggling. If you're buying energy exposure, know which business you're actually buying. A 33% margin gas producer and a 2% margin refiner both show up in the same ETF, but they have nothing in common except the sector label.
The grade distribution hasn't changed much since April. That stability is either comforting or concerning, depending on whether you wanted to see improvement. The sector found its level. Now it has to prove it can stay there.
