Masimo Exposes Politan’s Governance Hypocrisy

Highlights Quentin Koffey’s Actions That Have Flown in the Face of Good Governance

Masimo Corporation (“Masimo” or the “Company”) (NASDAQ: MASI) today highlighted the actions taken by Politan and Quentin Koffey since Masimo’s 2023 Annual Meeting of Stockholders that directly contradict their purported commitment to good governance.

Over the past twelve months, we believe Politan’s Quentin Koffey has repeatedly acted against the best interests of Masimo and its stockholders. The summary provided below shows stockholders and the public the numerous actions Politan has taken to advance its own agenda at the expense of Masimo’s governance and stockholder value.

We encourage all our stockholders to vote FOR Joe Kiani and Christopher Chavez using the GOLD proxy card to protect Masimo’s future and the value of your investment.

Politan Waged a 2023 Proxy War Against Masimo Under the Guise of Promoting Good Governance…

…Yet over the last 12 months, in direct contradiction to his promises, Quentin Koffey has…

• rejected all efforts to expand the Board and enhance oversight, including offers to add Politan’s own nominees
• refused to fulfill even the most basic director responsibilities, including signing the 2023 Annual Report and approving earnings releases
• deceived the Special Committee he chaired, and we believe subsequently lied to investors about the true reasons for his failure
• proposed Masimo disenfranchise shareholders by having the CEO and the Lead Independent Director "swap" classes for this election, violating core principles of good governance and Delaware law simply to make his own proxy contest less difficult
• repeatedly confirmed Politan’s nominees would vote as a bloc, ensuring a deadlocked Board and demonstrating their lack of independence and commitment to Politan's agenda over shareholder interests
• sought to override a possible shareholder vote against Mr. Kiani by reappointing him to the Board, actively repudiating the wishes of the shareholders
• pushed for unqualified board members, including a supposed financial expert whose questionable track record includes investing in a Ponzi scheme
• formally requested the Board invalidate a properly-noticed record date to disenfranchise a large shareholder who had voted against Politan’s slate (and, by extension, any other holders voting against the Politan slate)

Politan’s self-righteousness is not a “commitment” to good governance – it is a commitment to advancing its own agenda by any means available
