The legal action, filed by the firm Bronstein, Gewirtz & Grossman, asserts that Pentwater held an economic interest in approximately 51% of Avis outstanding shares. According to the complaint, the defendants failed to disclose their influence, utilizing a mix of common stock and cash-settled swaps to drive market volatility. By forcing short sellers to cover their positions at peak prices, Pentwater allegedly secured a financial windfall at the expense of other market participants.

Investors who acquired Avis securities during the specified window have until September 29, 2026, to petition the court for lead plaintiff status. While the case proceeds, the law firm is soliciting additional claimants, operating on a contingency fee basis. Founding partner Peretz Bronstein maintains that the litigation is intended to restore capital and enforce corporate accountability within the automotive rental sector.
