- Avis Budget Group's shares rose 8% on news of a $650 million settlement with Pentwater Capital Management, resolving a legal dispute over short-swing profits. Pentwater's prior actions, including a large stake disclosure and subsequent stock dump, had previously caused significant volatility and a sharp decline in Avis's stock. This settlement removes a major overhang and potential legal risk for Avis, which is a positive development for the company and its shareholders.

Investing.com -- Avis Budget Group (NYSE: CAR) is shifting into high gear. Shares of the car rental giant accelerated 8% in after-hours trading Monday following news of a massive $650 million cash settlement with hedge fund Pentwater Capital Management LP.
The hefty payout resolves a bitter legal dispute over illicit "short-swing" profits. According to a Securities and Exchange Commission filing, Avis aggressively pursued the funds under Section 16(b) of the Securities Exchange Act, forcing Pentwater to return the gains from a highly controversial stock dump.
The drama traces back to the wild trading days of April 2026. Pentwater—then the company’s second-largest shareholder—helped ignite a massive short squeeze by disclosing a huge stake in Avis, rocketing the stock up more than 600% over just a few weeks.
But the euphoria screeched to a halt. On April 22, immediately after Avis hit a record-high close of nearly $714, Pentwater abruptly unloaded 4.3 million shares at prices ranging between $250 and $700. The massive exit crashed Avis shares by 38% that day, triggering a brutal 48% nosedive in the following session.
Avis CEO Brian Choi didn’t mince words when pointing the finger at the hedge fund for the collapse:
"Given the quantum of shares sold in such a short span of time, our stock price experienced a significant decline. It seems the only insider active during this period of excess volatility was Pentwater Capital."
To close the book on the fiasco, Pentwater has agreed to hand over $650 million in cold, hard cash. The deal is still pending final court approval, requiring a judge to formally agree that Avis diligently pursued its claims and that the nine-figure payout is fair, reasonable, and adequate.
