Rosen Law Firm is reminding purchasers of Avis Budget Group securities about a September 29, 2026, deadline to seek appointment as lead plaintiff in a securities class action. The proposed class covers investors who bought Avis common stock or other securities between February 20, 2025, and April 21, 2026, inclusive, including those who purchased shares to cover a short position. The lawsuit alleges that Pentwater Capital Management LP and Matthew Halbower, Pentwater’s CEO, CIO and Founder, manipulated Avis securities. It claims Pentwater held an approximately 51% total economic interest in Avis through stock and cash-settled swaps as of March 2026, and that aggressive stock purchases caused unusual volatility and a short squeeze (rapid buying by short sellers to limit losses). No class has been certified. Investors may seek representation, remain absent class members, or take no action, and potential recovery does not depend on serving as lead plaintiff.
