Upon completion, Masimo Corporation (NASDAQ:MASI) will continue to be a standalone business unit and brand within Danaher’s Diagnostics segment and will operate autonomously.

Danaher shares our commitment to investing in talent and innovation and will be an ideal fit to help power the next chapter of Masimo.
