Politan comments on Masimo’s latest attempt to block a fair shareholder meeting Page 1

Politan Capital Management (together with its subsidiaries, “Politan”), an 8.9% shareholder of Masimo Corporation (“Masimo” or the “Company”) (NASDAQ: MASI), today issued the following statement:

“With its motion for a preliminary injunction denied, Masimo has decided this Saturday to ask the California federal court to invalidate Politan’s current proxy card. This follows the court’s hearing on Friday on Masimo’s request to postpone the annual meeting. Masimo is justifying these requests by claiming that it has been greatly prejudiced by Politan’s disclosure that the court denied the company’s request for a preliminary injunction on Thursday, when it should have been made public on Friday instead.
