Masimo rose 25% in premarket trading on Tuesday.

Danaher (DHR) is nearing a roughly $10 billion deal to acquire U.S. medical technology firm Masimo (MASI), the Financial Times reported, citing people familiar with the matter.
A deal for the California-based Masimo could be announced as early as Tuesday, provided it does not hit any last-minute snags, the report said. That deal value represents a premium to its nearly $7B market capitalization at Friday’s close.
