Everything the company sold, before any costs. Each bar sums the four quarters ending there — a full year, brought up to today.

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. One bar per fiscal year, as filed. Stops at the last completed year.

What was left after every cost, including tax. Each bar sums the four quarters ending there — a full year, brought up to today.

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.

Cash left over after running and maintaining the business. One bar per fiscal year, as filed. Stops at the last completed year.

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 quarter on its own, so seasonal highs and lows are visible.
