Large pay packages are becoming more common among fast-growing startups, especially since Tesla Inc.'s success unleashed a flood of cash in the electric vehicle market. Such agreements are similar to the one that helped Tesla CEO Elon Musk become the world's richest person, according to Dayna Harris, a partner at executive compensation firm Farient Advisors. Last year, at least 15 corporate leaders received awards worth $100 million or more, a threefold increase from Musk's award in 2018. As of 12:32 p.m. Wednesday in New York, the stock had fallen another 4.3 percent.
