How does Celestica break its business down?
Celestica (CLS) reports revenue by business across 2 parts — ATS and CCS. Each is extracted from the segment footnotes and tracked over time.
Where does Celestica's segment data come from?
Segment breakdowns are pulled from the segment footnotes in Celestica's SEC filings (the XBRL dimensional tags), so every line ties back to a reported figure. Switch between quarterly, annual, and TTM, or open any segment for its full history.
