Sources and method

SEC EDGAR

Every company's SEC record gives its fiscal year end and the period end date of every 10-Q, 10-K and 20-F, which is where the fiscal calendars come from. Every 8-K with Item 2.02 (Results of Operations) is an earnings release: its date and time come from the SEC's acceptance stamp, converted to New York time. Before 9:30 am is before the open, from 4:00 pm is after the close.

Nasdaq's earnings calendar

Expected dates for the coming weeks come from Nasdaq's public earnings calendar (data from Zacks). They are stored as Estimated until the company announces a date.

Company announcements

Each morning a model with web search (Gemini) looks for the company's own announcement of an upcoming date, for a handful of Estimated dates coming up soon. A find counts only if it is on the company's own site or a press-release wire, the date is within two weeks of the expected one, and the page mentions it. It is then shown as Confirmed with an Unverified badge until it is checked by hand. Anything that fails a check is thrown out and logged.

Projections

When nobody has a date for a coming quarter, the same quarter's report date a year earlier is moved forward 52 weeks, keeping the weekday. These are marked Projected and are only a guide.

Refresh schedule

Every morning at 05:30 UTC. On Sundays the refresh re-reads every company from EDGAR and sweeps thirteen weeks of Nasdaq's calendar.

How the list grows

Public companies in the companies.fru.dev registry are added as the daily run finds them. Growth, shown as "+N in 30 days", counts only companies first seen after 2026-09-22; the hand-checked launch list is the starting point, and seed, research or backfill loads never count as growth.

Not investment advice

Dates from SEC EDGAR filings, company announcements and Nasdaq's earnings calendar, refreshed every morning; dates an agent finds in an announcement are marked unverified until checked by hand. The list grows as new public companies are added. Not investment advice; check the company's investor relations site before relying on a date. Logos via logo.dev; trademarks belong to their owners. Anonymous usage stats via Google Analytics. Dates can move and sources can be wrong.

Corrections

Every company page has a Suggest a correction link. Each suggestion is checked by hand against its source before anything changes.
