How Watsco Inc. scores

As of October 18, 2026, Watsco Inc. scores 6.7 out of 10 on the Lemma Quality Score, a reading of solid quality. This band covers companies that do several things well but not everything, so the pillar detail below matters more than the headline. Nothing in it comes from the share price or from forecasts: it is Watsco Inc.’s own reported numbers, scored pillar by pillar.

Set against 270 Industrials companies, Watsco Inc. lands at the 80th percentile, among the stronger quarter of the group. For reference, the middle of the group scores 5.6 and a company needs 6.5 to reach its top quarter, which leaves Watsco Inc. above the median.

Pillar by pillar

Profitability

On profitability, Watsco Inc. scores 5.6, an average reading. Its peers have a median of 4.9 across 262 Industrials companies, which places it above them, at the 62nd percentile. An average profitability reading usually means the company earns a fair return without obvious pricing power, so the other pillars decide more of the story.

Solvency

Watsco Inc.’s solvency score is 9.4 out of 10 (strong). Against a median of 7.1 among 241 Industrials companies, that is well above the group and the 87th percentile. Strong solvency points to a balance sheet that can carry its debts comfortably, with interest well covered and little pressure from creditors.

Growth

On growth, Watsco Inc. scores 4.6, an average reading. Its peers have a median of 5.4 across 216 Industrials companies, which places it below them, at the 39th percentile. Average growth reflects a business expanding at roughly the pace of its sector, without a clear acceleration or decline.

Efficiency

On efficiency, Watsco Inc. scores 8.0, a strong reading. Its peers have a median of 6.2 across 264 Industrials companies, which places it well above them, at the 90th percentile. Efficiency at this level means the company needs comparatively little capital to produce what it sells.

Predictability

Watsco Inc.’s predictability score is 6.7 out of 10 (average). Against a median of 5.0 among 267 Industrials companies, that is well above the group and the 80th percentile. An average predictability reading means results have wobbled about as much as is normal for the sector.

Strongest and weakest pillar

The gap between Watsco Inc.’s best and worst pillar is wide: solvency at 9.4 against growth at 4.6, 4.8 points apart. An average of two readings this different deserves a closer look than the headline number. Leading with solvency is a defensive strength: it protects the business more than it grows it. Slow growth limits how fast the business can compound, even when everything else is in order.

What would move the score

The pillar with the most room to move the score is growth. If it rose to the median of Industrials companies, 5.4, Watsco Inc.’s overall score would go from 6.7 to about 6.9. The weights add up to 100 points (profitability 25, solvency 20, growth 20, efficiency 15, predictability 20), and Watsco Inc. has a reading on every pillar.

Limitations

This score is a systematic, backward-looking read of reported fundamentals. It does not judge valuation, management quality, competitive moat, or future prospects, and can be distorted by one-off items or unusual accounting. Treat it as a starting point, not a recommendation.

Five pillars, each scored from 0 to 10 against sector-aware benchmarks and then weighted into one overall reading: profitability, solvency, growth, efficiency and predictability. Everything comes from reported financials, and nothing comes from price, sentiment or forecasts.

How current is this score?

This page last changed on October 18, 2026. The score moves with the financial statements, so the page changes when a new filing moves the reading rather than on a schedule. Live figures for WSO are in the app.

Does a high score mean the stock is cheap?

No. Quality and valuation are separate questions, and a good business at the wrong price is still a bad purchase. Score the business here, then price it with a DCF you control.
