The company became the latest electric vehicle start-up to fail to meet investors’ expectations after a high-profile public debut.

On the social media platform X, which Mr. Musk owns, reactions to a vote that reaffirmed Mr. Musk’s $45 billion package were buoyant.

The vote was seen as a referendum on his management of the electric car maker and on the limits of executive pay.

With the addition of Alpine, BMW, Isotta Fraschini and Lamborghini, nine manufacturers are racing this year.

The team won so often in the early years that its drivers were called the Bentley Boys.

A huge run-up in the stock’s value followed a 2018 vote on Elon Musk’s compensation package. But investors have recently become less enamored.
