We were able to find the annual revenue and employee count for Tesla from 2008 to present. We could not find either data point for years 2003 through 2007. All the data we were able to find is included in the attached spreadsheet.
All the data provided for years 2008 to present was expressly provided and thus did not require any estimates or assumptions. With regard to annual revenue and employee counts for 2003 through 2007 (that we ultimately weren't able to find), we looked for that information by using three research strategies. First, we reviewed Tesla's investor relations documents published on its website, such as annual SEC filings that stated the company's annual revenue and employee count. While those documents date back to 2005, the reports we sought (from 2003-2007) either weren't able to be viewed or didn't provide the information we were looking for. Second, we checked databases such as Macro Trends and Statista for that information. While there was revenue and employee-count data for Tesla within those sources, neither of those sources provided such data for years 2003-2007. Third, we conducted broad searches for any articles that might have mentioned the company's annual revenue and/or employee count for any of the years from 2003-2007. That research approach also did not yield either of the data points for any of the years (2003-2007), as the only mentions we found of such in articles were from years 2008 or later. Accordingly, we entered NA in the respective cells of the spreadsheet for years 2003-2007.
