Did you own Masimo ($MASI) when the company acquired Sound United? The company has since agreed to a $33.75M investor settlement over claims that shareholders were misled about the expected benefits of the acquisition and the company's growth outlook. According to the lawsuit, investors were not given an accurate picture of demand trends and inventory levels following the deal. After Masimo lowered guidance and disclosed weaker-than-expected performance, the stock price fell and investors filed suit. The settlement covers investors who purchased shares between May 4, 2022 and August 8, 2023, and the case is currently accepting late claims. If you held $MASI during that period, it may be worth reviewing your records and checking whether you qualify for a recovery. https://11th.com/cases/masimo-investor-lawsuit

$MASI claim deadline is April 28 Masimo settled $33.75M with investors over claims it overpromised on its $1B acquisition of Sound United (Denon, Bowers & Wilkins), then quietly cut revenue guidance and reported weak demand just a year later.
