Business Strategy and Outlook
| David Whiston |Gentex manufactures auto-dimming rear- and side-view mirrors that use electrochromic technology. These mirrors automatically darken to eliminate headlight glare for drivers and have many other applications. With about 2,000 patents worldwide, some valid through 2047, and nearly 90% market share, up from 77% in 2003, Gentex has a narrow economic moat it should be able to protect for a long time, in our opinion.
