Several law firms have announced investigations and class action lawsuits against various companies, including Endava, plc (DAVA), American Airlines Group Inc. (AAL), and iLearningEngines, Inc. (AILE). Glancy Prongay & Murray LLP is investigating Endava on behalf of investors, while Robbins Geller Rudman & Dowd LLP has filed a class action lawsuit against American Airlines, citing an 'unsustainable' sales plan that allegedly caused significant losses for shareholders. The lawsuit covers the period from November 2, 2023, when American Airlines projected its earnings for 2024, to April 30, when those projections fell short. Additionally, the Law Offices of Frank R. Cruz are investigating Definitive Healthcare Corp. (DH) and have reminded investors of looming deadlines in class action lawsuits against Seritage Growth Properties (SRG) and Stellantis N.V. (STLA). iLearningEngines, Inc. has come under scrutiny as well, with multiple firms, including Rosen Law Firm and Glancy Prongay & Murray LLP, encouraging investors with losses to inquire about potential class action lawsuits. The investigations highlight ongoing concerns regarding corporate governance and financial disclosures across these companies.
