Class action lawsuit puts recent Avis Budget Group trading under the microscope

Avis Budget Group (CAR) has become the focus of fresh legal scrutiny after a new class action lawsuit accused major shareholder Pentwater Capital Management and its CEO of manipulating trading in the company’s stock.

The complaint, filed in the United States District Court for the Middle District of Florida, covers investors who owned or bought Avis securities between February 20, 2025 and April 21, 2026. It centers on alleged trading activity that coincided with a sharp spike and subsequent collapse in the Avis share price.

The class action lands at a sensitive time for Avis Budget Group, with the stock at US$141.46 and short term sentiment mixed. The 1 day and 7 day share price returns of 2.79% and 1.35% contrast with a 30 day share price return that is down 11.32%. Over longer periods, the 1 year total shareholder return is down 4.38% and the 3 year total shareholder return is down 35.62%, even though the 5 year total shareholder return is up 63.17%, which suggests longer term holders have still seen gains.

The legal overhang, recent spike and pullback, and a share price of US$141.46 leave Avis Budget Group looking very different to just a few months ago. Do those risks still justify the potential reward at today’s valuation?

Most Popular Narrative: 5.5% Overvalued

The most followed narrative currently places Avis Budget Group's fair value at $134.14 compared with the last close of $141.46, which implies a small premium that hinges on a very specific earnings recovery story.

The launch and rapid scaling of Avis First, a premium rental offering, could be fueling expectations of significant revenue and margin expansion, as investors anticipate a sustained uplift in average revenue per day (RPD) and market share capture from price-insensitive travelers; this optimism may not fully account for competitive responses or changing customer preferences, increasing the risk that future revenue and net margin improvements fall short of current valuations.

Want to see what has to go right for Avis Budget Group at the same time? The narrative leans on measured revenue growth, a margin reset, and a future earnings multiple that all need to line up. Curious which of those assumptions carries the most weight in the fair value math.

Result: Fair Value of $134.14 (OVERVALUED)

However, there are clear risks to this Avis Budget Group narrative if premium offerings underperform or if alternative mobility services take more share than analysts currently factor in.

Another view on Avis Budget Group valuation

The earlier narrative suggests Avis Budget Group trades at a premium to a fair value of $134.14. Yet on simple sales based numbers, the stock looks very different. A P/S ratio of 0.4x compares with 1.2x for the US Transportation industry and 2x for peers, while the fair ratio is 0.7x. That gap points to meaningful valuation risk if the market moves closer to peer levels, but it also raises the question of whether investors are underpricing a possible recovery.
