How do I find a company’s financial data historically?
If you are only looking at a few companies, Capital IQ, and Refinitiv Workspace, provide spreadsheet financials in annual and quarterly format (as reported and/or in standardized templates). If you are looking at hundreds or thousands of companies, Worldscope and Compustat (available via WRDS have deep historical coverage as well a the ability to pull data for a large number of firms at one time.
