Intrusion Inc
How the company evolved, year by year. Revenue and debt come from the annual reports — for most companies, the 10-K filings with the SEC since 2009; dividends from the payments themselves.
The bars are a balance on the closing date; the lines are what happened during the year. Revenue above equity is ordinary, not an anomaly — it means the company turns its capital over more than once a year.

Median, not average: a single year of near-zero profit produces a P/E of 400 and would drag an average on its own. P/E years above 200x are left out, the same cut the fair price uses — so this median matches the “its own history” method below. Price and EPS have no median: they are series that grow.
