ClaimsFiler said Avis Budget Group, Inc. investors have until September 29, 2026 to seek appointment as lead plaintiff in a securities class action tied to trading in the company’s shares between February 20, 2025 and April 21, 2026, including investors who bought common stock to cover a short position. The case, pending in the United States District Court for the Middle District of Florida, alleges that Avis and certain executives failed to disclose material information and that Defendants Pentwater and Halbower manipulated the market for Avis securities. The complaint says Pentwater, which held an approximate 51% total economic interest in Avis through stock and cash-settled swaps (derivatives settled in cash) as of March 2026, aggressively bought shares during the class period, driving unusual volatility and a short squeeze (rapid buying by short sellers covering losses). Avis shares reached an intraday high of $765.94 on April 21 after opening at $147.52 on April 1, then fell 74.51% to close at $182.005 on April 28, 2026. ClaimsFiler directed investors to its case page and said lawyers at Kahn Swick & Foti, LLC are available to discuss legal options.
