Shares of Avis Budget Group (NYSE:CAR) surged in after-hours trading after the company disclosed that hedge fund Pentwater Capital Management LP has agreed to pay $650 million in cash to resolve a legal dispute over profits tied to a rapid stock sale.
The company reported the agreement in a Securities and Exchange Commission filing that describes a recovery effort under Section 16(b) of the Securities Exchange Act. Avis said it sought to recover so-called short-swing profits, and the settlement requires Pentwater to return proceeds from a sales program that followed a period of extreme price appreciation.
Background and the trading episode
The case centers on trading in April 2026, when a short squeeze drove the stock up aggressively. Pentwater, at that time the companys second-largest shareholder, disclosed a large stake that helped propel the share price higher by more than 600 percent over a matter of weeks.
Trading reversed sharply after an especially large sale on April 22. According to the filing, that day - immediately after the stock recorded a record-high close near $714 - Pentwater sold 4.3 million shares at prices that ranged between $250 and $700. The disclosure says that transaction pushed the stock down about 38 percent that day, and that the subsequent session saw a further decline of 48 percent.
"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."
The quoted comment is attributed to Avis's chief executive, who criticized the timing and scale of the sales that coincided with the extreme volatility.
Settlement terms and next steps
Pentwater has agreed to transfer $650 million in cash to resolve the dispute. The payment is subject to final court approval. A judge must find that Avis pursued its claims diligently and that the proposed nine-figure payment is fair, reasonable, and adequate before the settlement is finalized.
Until a court signs off, the agreement remains conditional. The SEC filing frames the companys recovery under the statutory mechanism available for recapturing short-swing profits, but it leaves the ultimate judicial determination to the court handling the matter.
Market reaction and context
News of the settlement prompted an immediate market response, with the stock moving sharply higher in after-hours trading on the day the disclosure was made. The filing and the size of the proposed payment underscore the scale of the trading episode and the legal exposure the company identified from the rapid series of transactions in April 2026.
While the settlement would represent a substantial recovery if approved, the filing emphasizes that the payment is conditioned on judicial review. The company will need court approval to close the record on the matter.
Summary
Avis Budget Group disclosed that hedge fund Pentwater Capital Management LP has agreed to a $650 million cash settlement to resolve claims under Section 16(b) related to a volatile short-squeeze episode in April 2026. The settlement follows an April 22 sale of 4.3 million shares by Pentwater at prices between $250 and $700 that coincided with sharp intraday declines. The agreement remains subject to final court approval, which requires a judge to determine that the recovery effort and the payment are fair and adequate.
