Form 10-Q

The quarterly report — condensed financial statements and an updated management discussion, filed for each of the first three fiscal quarters. It is reviewed by the auditor but not audited, and the fourth quarter never gets one: Q4 lives only inside the annual report's full-year figures.

Formula

Fiscal year = 3 × 10-Q + one 10-K (the fourth quarter reports only inside the annual)

Drivers — what actually moves it

Cadence: due within 40–45 days of quarter end by filer size — the fastest recurring full-statement read.
Assurance: reviewed, not audited — quarterly figures carry lighter assurance than the 10-K's.

Where it comes from

Not a filing concept — the quarterly form itself; its concepts carry quarterly periods. On EDGAR under the company's filings, form type 10-Q — three per fiscal year, none after the fourth quarter.

Sector caveats — where this breaks

A missing standalone Q4 is structural, not an omission — deriving it means subtracting nine months from the year, with the seams that implies.
