3M by the numbers
The manufacturer behind Post-it Notes and Scotch tape. In recent years it has been weighed down by lawsuits over PFAS chemicals and military earplugs.

How it's calculated
- Returns use each year's last closing price, adjusted for stock splits with dividends reinvested. Read every figure as "bought at the end of one year, sold at the end of another."
- Taxes, trading fees and inflation are not included; all amounts are nominal US dollars.
- Data runs through the end of 2024. Past returns don't guarantee future results, and this page is not investment advice.
