According to a filing with the Securities and Exchange Commission (SEC)TeslaJerome Guillen, the executive and president, left on June 3 and has sold about $274 million worth of shares after exercising stock options since June 10.

Gillen is expected to sell 215718 shares at a price of $129 million that day and reduce his holdings of 145289 shares worth $89.6 million on June 14, according to filings with the Securities and Exchange Commission on Tuesday. On June 10, he reduced his holdings of 90111 shares worth $55 million.

Gillon, a former Mercedes engineer, has been working for Tesla, Inc. since 2010 and was in charge of the company's vehicle business before he was appointed president of Tesla, Inc. 's heavy truck division in March.

The departure of Ji Lun, one of Tesla, Inc. 's four leaders, has raised concerns about Tesla, Inc. 's future car projects, such as semi-electric trucks and a new battery called 4680 battery.

Gordon Johnson, an analyst at GLJ Research, estimates that Gillon has reduced his shares in Tesla, Inc. from 1.3 million a year ago to about 150000 on Friday.

"if Tesla, Inc. is about to achieve technological and independent breakthroughs, achieve breakthrough delivery / earnings in the second quarter, and dominate the field of electric vehicles," he said in a report. Why do many people think that the company's second most important person (Jerome Gillen) sold $274 million worth of Tesla, Inc. shares? "

Daniel Ives, an analyst at Wedbush Securities, said: "this may cause some dissatisfaction among investors." He added that investors would be watching closely to see if he sold more shares.

Stock options give employees and executives the right to buy shares of the company at a specific price within a certain period of time. When the stock price is higher than the exercise price, they can buy shares at a discount.

It is not clear how much Gillen paid for exercising the option.
