CAR INVESTOR ALERT: Avis Budget Group, Inc. Investors with Substantial Losses Have Opportunity to Lead the Avis Class Action Lawsuit – RGRD Law

A class action lawsuit has been filed against Pentwater Capital Management LP and its CEO Matthew Halbower, alleging they accumulated a massive stake in Avis Budget Group while artificially driving up the stock price through a short-squeeze dynamic. The complaint claims that after the stock peaked at $847.70 per share on April 21, 2026, Pentwater sold 4.3 million shares over two days for $1.75 billion, causing the share price to plummet. Investors who purchased Avis securities between February 20 and April 21, 2026 can seek appointment as lead plaintiff by September 29, 2026.
