MacKenzie Bezos, Jeff Bezos' now former wife, will receive 25% of the Amazon.com (AMZN) - Get Amazon.com, Inc. Report stock that the couple formerly held together, according an announcement she made on Twitter on Thursday. 

Jeff Bezos will keep the remaining 75% stake, as well as the voting rights for the 25% of the shares now owned by MacKenzie, a novelist who was deeply involved in the early days of founding Amazon.

Prior to the split, the couple owned about 78.8 million shares of Amazon, or 16% of the outstanding shares of the company. After dividing up the shares, MacKenzie will own about 4% of the company, currently worth about $35.9 billion, and Jeff will own the remaining 12%, which is worth about $107.6 billion.  

In her tweet, MacKenzie said she was "grateful to have finished the process of dissolving" their marriage and that she was "happy" to be giving her ex-husband the Amazon stake and voting rights, as well as the entirety of their joint interests in the Washington Post and space exploration company Blue Origin. She said the moves would "support [Jeff's] continued contributions with the teams of these incredible companies."

Amazon shares were down 0.5% to $1,812.51 on Thursday afternoon. When Jeff Bezos first announced the couple was splitting in January, there were concerns about whether the divorce would affect the Amazon's CEO's ownership stake and control of the company.
