Joe Kiani, Masimo CEO, removed from board following proxy battle; Politan secures two seats.

• Politan secured two board seats at Masimo, winning out against founder Joe Kiani and another director in a shareholder vote.
• Darlene Solomon and Bill Jellison, both polite nominees, will be added to the board along with two others who were previously added in a proxy fight.
• If Politan wins, Kiani may have to leave as CEO.

Politan Capital secured two board seats at the medical technology company, winning out against founder and CEO Joe Kiani and another director, Chris Chavez, in a shareholder vote.

Politan investment chief Quentin Koffey and former Johnson & Johnson executive Michelle Brennan, who obtained board seats in a prior proxy fight last year, will be joined on the Politan board by nominees Darlene Solomon and Bill Jellison. Masimo shares rose more than 2% in extended trading.

The four directors expressed their excitement to collaborate with the Healthcare and Consumer employees in order to enhance Masimo's performance, following the vote on Thursday.

According to a source who requested anonymity to discuss non-public information, Politan's nominees received roughly twice as many votes as Kiani and Chavez combined.

The legal battle between Masimo and Politan during their proxy fight was intense. Masimo accused Politan of making errors in its proxy statement, while Politan accused Masimo of manipulating the vote count with the help of a powerful shareholder ally.

Despite Koffey's contempt of court for revealing the judge's decision, Masimo's request for injunctive relief was rejected. As a result, Politan's victory may lead to the departure of CEO Kiani and operating chief Bilal Muhsin. Both Kiani and Muhsin have stated that they would resign if Kiani was removed from the board.
