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.
Price & Valuation
Multiples computed on the strict TTM/EV methodology — today's snapshot against the industry, and each ratio recomputed as of past filing dates.
Valuation over time computed as of each quarter's filing date
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.
