Activist Politan planning second proxy battle at Masimo, WSJ reports

An activist investor who holds two seats on the board of Masimo is planning a proxy fight for two more, The Wall Street Journal’s Lauren Thomas reports. Politan Capital Management, founded by veteran activist Quentin Koffey, plans to nominate two director candidates to the company’s six-person board, according to people familiar with the matter. Politan has held a roughly 9% stake in Masimo since 2022. It won a pair of board seats last year at Masimo’s annual meeting, including one for Koffey, the author adds.
