LOS ANGELES, March 11, 2026 (GLOBE NEWSWIRE) -- The Portnoy Law Firm advises Masimo Group, (“Masimo" or the "Company") (NASDAQ:MASI) investors that the firm has initiated an investigation into possible securities fraud, and may file a class action on behalf of investors.

Investors are encouraged to contact attorney Lesley F.

Masimo’s stock price fell $15.98, or 11.8%, to close at $120.02 on May 8, 2024, thereby injuring investors. This occurred following the news on May 7, 2024, that Masimo disclosed receiving a Department of Justice (“DOJ”) subpoena back in February. The government request was “seeking documents and information related to the Company’s Rad-G and Rad-97 products,” which included “information relating to complaints surrounding the products and the Company’s decision to recall select Rad-G products in 2024.”

The Portnoy Law Firm represents investors in pursuing claims caused by corporate wrongdoing. The Firm’s founding partner has recovered over $5.5 billion for aggrieved investors. Attorney advertising. Prior results do not guarantee similar outcomes.
