Amazon CEO Jeff Bezos Just Got A Lot Richer by Lucinda Shen @FortuneMagazine April 29, 2016, 12:12 PM EDT E-mail Tweet Facebook Linkedin Share icons Amazon amzn CEO Jeff Bezos has been known to be a grueling, micromanaging, and, at the same time, a brilliant boss. Looks like that combo has paid off for him. On Thursday, the retail and tech giant he founded reported earnings that blew away Wall Street estimates, sending shares up 10% in trading Friday. In turn, Bezos also brought in a pretty penny overnight—roughly $5.1 billion based on his shares in the company. Bezos is no stranger to seeing his wealth multiply overnight. In 1998, a year after Amazon went public, his net worth was $1.9 billion. One year later, that number became $9 billion, according to Wired. By 2010, Bezos’s wealth grew to $12.6 billion, and by the start of 2015, his’ net worth was about $28 billion. After Amazon’s stock’s steep upward rise Friday, Bezos’s worth shot up once again to $59 billion, making him No.4 on Bloomberg’s Billionaire Index—displacing Mexican business mogul Carlos Slim who, in turn, lost $3.4 billion on Thursday, after his phone company, America Movil SAB reported weak sales. Bezos owns 17.6% of Amazon, or about 83 million shares. Due to his large stake in the company, he does not get additional stock awards as part of his compensation package. Instead, Bezos earned a base salary of $81,840 in 2015. Amazon also paid $1.6 million for his personal security. Neither his salary nor his security pay has changed in the past three years.
