Innventure, Inc. and certain senior executives face a securities class-action lawsuit alleging that the company overstated the prospects and revenue contribution of Accelsius’s DarkNX data-center project. Schall, Brown & Schwartz LLP said the complaint alleges there was insufficient evidence that an artificial-intelligence data center existed or had entered construction, making Accelsius’s expected revenue targets misleading. The case covers investors who bought Innventure shares from November 17, 2025, through August 13, 2026, with an October 27, 2026, deadline to seek appointment as lead plaintiff. Innventure suspended its previously communicated 2026 Accelsius revenue and cash-flow expectations on August 13 after saying the deployment site was no longer available and the project had been removed from internal bookings. The company’s shares fell 55%, or $1.98, from $3.60 to $1.62 in the decline described in the latest case announcement. The class has not yet been certified, and investors who take no action may remain absent class members.
