How Diamondback Energy Inc. scores

Diamondback Energy Inc. (FANG) has a Lemma Quality Score of 4.5 out of 10 as of October 19, 2026, which reads as mixed quality. A mixed reading means the strengths and weaknesses roughly cancel out, and the case for the business depends on which pillars you care about most. Five pillars feed it, and every one of them is computed from what the company reported rather than from its share price.

Ranked with the 87 Energy companies Lemma publishes, the score sits at the 34th percentile, in the weaker half of its peers. The median across the group is 5.0, and the top quarter begins at 5.9, so Diamondback Energy Inc. is below the typical company here.

Pillar by pillar

Profitability

Profitability scores 3.9 out of 10, which reads as weak. The median across 84 Energy companies is 5.5, so Diamondback Energy Inc. is well below its peers on this pillar and ranks at the 39th percentile. Weak profitability means the business converts less of its sales and capital into profit than its peers, which can come from thin pricing power, high costs or a temporary squeeze.

Solvency

Solvency scores 6.5 out of 10, which reads as average. The median across 79 Energy companies is 6.5, so Diamondback Energy Inc. is in line with its peers on this pillar and ranks at the 49th percentile. Leverage in the middle of the range is rarely a problem in good years, and it is worth watching how quickly it would tighten in a weak one.

Growth

Growth scores 4.2 out of 10, which reads as average. The median across 66 Energy companies is 5.2, so Diamondback Energy Inc. is below its peers on this pillar and ranks at the 32nd percentile. Average growth reflects a business expanding at roughly the pace of its sector, without a clear acceleration or decline.

Efficiency

On efficiency, Diamondback Energy Inc. scores 4.7, an average reading. Its peers have a median of 5.5 across 81 Energy companies, which places it below them, at the 38th percentile. An average efficiency reading suggests the business turns its assets and earnings into cash at roughly the rate its sector does.

Predictability

Diamondback Energy Inc.’s predictability score is 3.5 out of 10 (weak). Against a median of 3.1 among 86 Energy companies, that is in line with the group and the 64th percentile. When results are this uneven, the averages behind the other pillars hide a lot of movement, and a longer history tells more than the latest year.

Strongest and weakest pillar

The profile is uneven. Solvency leads at 6.5 while predictability trails at 3.5, a gap of 3.0 points, so the overall averages a clear strength against a clear soft spot. A solvency lead means the balance sheet is the company’s strongest asset, a cushion that buys time when trading gets harder. A predictability shortfall means the record is volatile, so the averages behind the other pillars move more than they appear to.

What would move the score

Of everything that could lift Diamondback Energy Inc.’s score, profitability matters most. Bringing it up to the 5.5 median of Energy companies would take the overall from 4.5 to roughly 4.9. All five pillars could be scored, so the overall uses the full set of weights out of 100: profitability 25, solvency 20, growth 20, efficiency 15, predictability 20.
