The Simply Good Foods Company is the subject of an investigation by law firm Kaplan Fox & Kilsheimer LLP concerning potential securities law violations. The probe centers on the company's disclosures related to its June 2024 acquisition of the plant-based protein brand Only What You Need (OWYN) for $280 million.
The investigation follows two significant stock price declines. On October 23, 2025, shares fell over 17% after the company disclosed a "quality issue" with a raw material for OWYN sourced before the acquisition. The stock dropped again by over 18% on April 9, 2026, when Simply Good Foods announced a non-cash impairment charge of $249 million, with $187 million attributed to the OWYN brand.
