The Rosen Law Firm reminds purchasers of Avis Budget Group, Inc. (NASDAQ: CAR) securities—including common stock acquired to cover short positions between February 20, 2025, and April 21, 2026—of the fast-approaching September 29, 2026 lead plaintiff deadline in an ongoing securities class action lawsuit.
The Bottom Line
- Lead Plaintiff Deadline: Investors wishing to serve as lead plaintiff must petition the Court by September 29, 2026.
- Class Period: The litigation covers purchasers of Avis securities between February 20, 2025, and April 21, 2026.
- Core Allegation: The lawsuit targets Pentwater Capital Management LP and CEO Matthew Halbower for allegedly orchestrating a short squeeze through aggressive stock purchases.
Unpacking the Market Manipulation Allegations
According to court documents highlighted by The Rosen Law Firm, defendants Pentwater Capital Management LP and Matthew Halbower—who serves as Pentwater’s CEO, CIO, and Founder—faced accusations of orchestrating a scheme to manipulate the market for Avis securities. By March 2026, Pentwater held an economic interest of approximately 51% in Avis through a combination of physical stock and cash-settled swaps.
Here is the math: the lawsuit asserts that Pentwater leveraged its massive stake to drive aggressive purchases of Avis common stock during the designated Class Period. This buying activity triggered unusual volatility and a short squeeze, forcing short sellers to buy back shares at escalating prices to limit losses. But the balance sheet tells a different story regarding market integrity, as these price spikes allegedly inflated the value of Pentwater’s holdings artificially.
Litigation Deadlines and Shareholder Options
With the September 29, 2026 deadline looming, eligible investors face critical choices regarding their participation. A class action lawsuit has already been filed, though no class has yet been certified by the Court. Until formal certification occurs, individual investors remain unrepresented unless they retain private counsel of their choice.
