Italic rows are computed from reported lines — open a row's info icon for its formula. Values reflect the latest filing (restatements included); per-share figures on today's split basis. Click a value for its source filing. TTM: trailing twelve months through the latest reported quarter — flows sum the last four quarters, balances take the latest. 3Y/5Y/10Y columns are trailing CAGR from the newest fiscal year; blank where an endpoint is missing or negative. (G): the company's own guidance — a (G) column is a guided period not yet reported; a G marker shows how the reported figure landed against the guided range. Non-GAAP-basis guidance (*) is shown as stated and never judged against GAAP actuals.

Revenue Breakdown

Annual revenue as the company disaggregates it in its own XBRL filings. Years a component wasn't reported show a dash.

Share mode is each component's slice of the reported components that year — issuers rarely tag every revenue dollar, so slices need not sum to total revenue.
