Event Summary

A securities class action lawsuit has been filed against Pentwater Capital Management LP and its founder, CEO, and CIO Matthew Halbower, on behalf of investors who purchased Avis Budget Group securities between February 20, 2025 and April 21, 2026. The complaint, filed in the United States — United States District Court for the Middle District of Florida as Hakimian v. Pentwater Capital Management LP, et al., alleges that Pentwater, holding approximately 51% economic interest in Avis through stock and cash-settled swaps, engaged in aggressive purchases that artificially inflated Avis's stock price and triggered a short squeeze. Avis's stock surged to an intraday high of $765.94 on April 21, 2026, up about 419% from its April 1 opening, before collapsing 74.51% to close at $182.005 on April 28, 2026. The lawsuit claims defendants made false and misleading statements and failed to disclose material information, violating federal securities laws. Multiple law firms, including Bronstein, Gewirtz & Grossman, LLC, Rosen Law Firm, Kahn Swick & Foti, and ClaimsFiler, are soliciting investors to join the action, with a lead plaintiff deadline of September 29, 2026.
