All figures originate in public company filings (10-K, 10-Q, and earnings releases), aggregated through two tiers: a 20-year tier via Alpha Vantage for a growing set of companies, and a 4-year tier via Yahoo Finance for the rest of the 5,000+ company universe. Aggregators occasionally return stale or inconsistently adjusted values, so every page carries the same advice: verify against SEC EDGAR before relying on any figure.
The 4-year tier refreshes daily, largest companies first, with the rest of the universe on a rolling cycle. The 20-year tier grows as API quota allows; once a company's 20-year history is in place it is preserved, not overwritten. Each company page states its own last pull date, and data older than a week is labeled with its age.
From the raw statements the site derives a trailing ratio suite: profitability margins, capital efficiency (ROIC, ROE, ROCE), leverage and interest coverage, cash-flow quality (CFO/net income, FCF conversion), and historical valuation multiples. Every computed figure is trailing — derived from reported periods only. Ratios whose inputs are missing or too small to be meaningful are shown blank rather than published as noise.
By standing editorial and legal policy, TickerBase publishes no forward-looking numbers (no revenue or EPS estimates, no forward P/E, no PEG), no price targets, no analyst ratings, and no buy, sell, or hold verdicts. A date — such as when a company reports — is a fact and may appear; an estimate attached to that date may not.
The DCF workbench starts with its assumption sliders deliberately unset. Reference inputs (trailing revenue, share count, net debt) come from the latest filings; every assumption about the future is supplied by the reader, and the resulting per-share value belongs to the reader — it is not the publisher's view of what the stock is worth.
