Both on one scale, because both are money — the bar that is taller is the one that matters.
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.
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.
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.
$52.74MQ3 2026-3.3%
Everything the company sold, before any costs. Each bar sums the four quarters ending there — a full year, brought up to today.
-$33.28MQ3 2026+39.1%
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.
-$23.96MQ3 2026+45.5%-45.4% of revenue
What was left after every cost, including tax. Each bar sums the four quarters ending there — a full year, brought up to today.
-45.4%Q3 2026+43.7%
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.
-$32.17MQ3 2026+47.0%
Cash left over after running and maintaining the business. Each bar sums the four quarters ending there — a full year, brought up to today.
-$0.48Q3 2026+42.9%
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.
52.88MQ3 2026-1.1%
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.
23.3xQ2 2022-15.7%
Paid per unit of yearly profit. Periods with a loss, or profits too small for the ratio to mean anything, are left out — the line breaks rather than drawing through them. Each point covers the four quarters ending there — a full year, brought up to today.
