Getting ahead in the digital journey can lead to outsize success, as the story of dental supply company Henry Schein illustrates, reports Fortune.

It has turned its dull-as-mouthwash catalogue business into the leading platform for digital dentistry, and increasingly for other medical practices. In doing so, it has made big money for shareholders. Since its IPO in 1995, it has provided an annualized return to shareholders of 16%—one of the best long-term performances on the list and far above Berkshire Hathaway’s BRK.A 0.31% 10.1% over the same period.
