Form 10-Q
Form 10-Q is the quarterly report US public companies file with the SEC for each of the first three fiscal quarters, containing unaudited financial statements and management's discussion of results.
The 10-Q is the quarterly companion to the annual Form 10-K. Companies file three per year (the fourth quarter is covered by the 10-K). It includes unaudited but auditor-reviewed financial statements, MD&A explaining changes in results, updates to risk factors, legal proceedings, and disclosure controls.
The 10-Q usually arrives around the same time as the earnings report press release, but contains more detail: revenue by geography or channel, customer and partner concentration, stock-based compensation, and updates on litigation or regulatory matters. For ad tech companies, it can show subtle changes in take rate, cash collection from agencies, or new risks.
Large accelerated and accelerated filers must file within 40 days of quarter-end; other companies within 45 days. Filings are published on the SEC's EDGAR database.
Think of it like this
A 10-Q is like a quarterly progress report between the big annual exams: shorter, less formal, but still required.
An example
An SSP's 10-Q discloses that CTV revenue grew 30% year on year and that one DSP partner accounted for over a fifth of revenue in the quarter.
