What it owns and what it owes

Both on one scale, because both are money — the bar that is taller is the one that matters.

Cash and debt

Cash & InvestmentsTotal Debt

Cash counts short-term investments, not just the bank balance — technology companies park most of it in marketable securities, and leaving those out understates it several times over. Debt includes lease obligations.

Where the money goes

Cost of RevenueR&D ExpenseSG&A Expense

Only the three costs filers report consistently. Anything a company does not break out sits outside these bands, so the stack is not the whole cost base.

The rest of the series

Not on the overview because five charts is as much as one decision needs — but here in full, on one period switch. Each bar sums the four quarters ending there — a full year, brought up to today.

Total Revenue

$3.96BQ2 2026+38.1%

1Y: -48.50%2Y: -34.94%5Y: +41.51%

1Y: -26.63%2Y: +14.47%5Y: +227.67%

Operating profit before depreciation and amortisation — approximated from operating income, because no depreciation tag is reported consistently enough across filers to do better. Treat it as indicative. Each bar sums the four quarters ending there — a full year, brought up to today.

Profit margin

36.2%Q2 2026-15.1%

How much of every dollar of sales the company keeps as profit. A grocer keeps a few cents; a software company can keep half. Each point covers the four quarters ending there — a full year, brought up to today.

1Y: +109.00%2Y: +241.31%5Y: +877.16%

The same profit, split across every share. If this lags the profit chart above, the company is issuing shares and your slice is getting smaller. Restated onto today’s share count, so stock splits do not show as jumps. Each bar sums the four quarters ending there — a full year, brought up to today.

Shares outstanding

35.3MQ2 2026-0.1%

How many shares the profit is divided across. Rising is dilution; falling is the company buying itself back. Restated onto today’s basis, so splits do not show as jumps. Each point covers the four quarters ending there — a full year, brought up to today.

About this data

Everything above comes from Comfort Systems USA Inc.’s own filings with the SEC, as reported. No estimates, no analyst figures, nothing adjusted.

Not reported by this filer: R&D Expense, Total Operating Expenses, Interest Income, Net Interest Income, Non-interest Income, Non-interest Expense, Deposits, Loans, Short-term Investments, and Borrowings (total). Companies choose which XBRL tags to use, and anything untagged cannot be recovered — so these are blank rather than guessed.
