It was confirmed that a former senior executive who left Tesla after breaking up with CEO Elon Musk earlier this month sold 300 billion won worth of Tesla stock.



Jerome Gillen, who served as president of Tesla's truck business, filed a sell-off report for Tesla stock with these details to the US Securities and Exchange Commission (Reuters) yesterday (19th) local time, Reuters reported.



Gillen sold over 450,000 shares worth $274 million and KRW 310.1 billion of Tesla stock secured through stock option exercise three times starting on the 10th.



Gillen's stock option strike price is unknown.



Gillen, who left Tesla on the 3rd, was one of Musk's key advisers.



He joined Tesla in 2010 after working for Daimler, a German automobile company. He served as the president of the automobile business and then the president of the truck division, but suddenly announced his breakup with Tesla.



The reason for his resignation is unknown.



Gordon Johnson, an analyst at corporate analytics firm GLJ Research, said many are curious as to why the "second most important person at Tesla" sold the stock.
