Winston Score History

The full picture

3M makes thousands of everyday products used in homes, hospitals, factories, and offices. Its most famous product is the Post-it Note, but it also makes Scotch tape, industrial adhesives, safety equipment like respirators, and medical supplies. The company sells to consumers, manufacturers, healthcare providers, and construction companies around the world.

3M earns money by selling physical products across four business segments: Safety & Industrial, Transportation & Electronics, Health Care, and Consumer. It operates in nearly every country, generating roughly half its revenue outside the United States, which makes it one of the most geographically diversified manufacturers in the world. Its main competitive advantage is its large portfolio of patents and its long history of developing new materials and coatings. The biggest risk 3M faces is ongoing legal liability from lawsuits related to PFAS chemicals and defective combat earplugs, which have already cost the company billions of dollars in settlements.
