(Bloomberg) -- Politan Capital Management is seeking two more seats on the board of Masimo Corp., marking its second proxy battle at the health-care technology company in as many years. 

The activist investor has put forward Darlene Solomon, former chief technology officer at Agilent Technologies Inc., and William Jellison, ex-chief financial officer of Stryker Corp., for election, according to a statement on Monday.

Politan holds an 8.9% stake in Irvine, California-based Masimo. It said it supports a strategic review to separate Masimo’s consumer business but has concerns about “broken governance and lack of independent oversight” at the company. 

Politan’s move to boost its influence comes less than year after it succeeded it having its Chief Investment Officer Quentin Koffey and former Johnson & Johnson executive Michelle Brennan elected to Masimo’s board. Politan said on Monday that its efforts to engage with Masimo CEO Joe Kiani since have been unproductive. 

“Joe Kiani refused to give us basic information, denied us access to management, repeatedly held board meetings excluding us, and refused to even consider allowing any review of capital allocation or strategy,” Koffey said. 

Shares in Masimo have fallen almost 20% over the last 12 months, giving the company a market value of roughly $7.4 billion. 

“Mr. Koffey and Ms. Brennan have never been excluded from a board meeting and have been provided an enormous amount of information and data,” a spokesperson for Masimo said in a statement. “As a member of the audit committee, Mr. Koffey attends regular meetings with Masimo’s CFO, chief accounting officer, internal auditor, and external auditors.”
