Rosen Law Firm announced a securities class action lawsuit for investors who bought Honeywell Aerospace Inc. common stock on the open market between June 29 and September 1, 2026, inclusive. The lawsuit alleges that the company and other defendants failed to disclose supplier concentration and supply constraints affecting sales and profitability, as well as an investigation into potential False Claims Act violations tied to cybersecurity requirements for government contracts. Investors seeking to become lead plaintiff must ask the court for appointment by November 23, 2026. The firm says eligible investors may pursue compensation through a contingency fee arrangement without upfront fees or costs. No class has been certified, and investors may retain their own counsel, remain absent class members, or take no action for now.
