Investors Face September 29 Deadline in Avis Budget Market Manipulation Suit

The lawsuit alleges that Pentwater Capital Management LP and its founder, Matthew Halbower, engaged in a scheme to manipulate the value of Avis stock. By March 2026, Pentwater held a 51% economic interest in the company through a combination of equity and cash-settled swaps. According to the complaint, the firm leveraged this position to trigger aggressive purchasing activity, creating artificial volatility and forcing a short squeeze that inflated the price of Avis securities for their own financial gain.

Rosen Law Firm, which is representing the plaintiffs, maintains that investors who suffered losses during this period may be eligible for compensation. While the case is currently proceeding, no class has been certified, meaning investors are not yet represented by counsel unless they choose to retain one. Those wishing to participate in the litigation or serve as a lead representative must finalize their filings by the September 29 cutoff. Participation does not require the payment of out-of-pocket fees, as the firm operates on a contingency basis.
