Where the numbers come from
Financial figures are the values Clean Harbors Inc tagged in its own SEC filings (XBRL), taken from the latest filing for each period, so restatements replace older figures. Revenue, profit and cash flow are for full fiscal years unless marked as the last twelve months, which is the sum of the four most recent quarters. Where a company reports only the full year, the fourth quarter is the year minus the first three.
Prices are delayed end-of-day market data in the listing currency, and market cap moves with the price. P/E is shown only when earnings per share are positive. Nothing here is investment advice.
