Snap Inc. said Chief Financial Officer Tim Stone is leaving to pursue unspecified opportunities. He had joined Snap just eight months ago after two decades at Amazon.
A number of top executives have left Snap in recent months. Stone had been broadly seen as someone who might bring more stability to Snap's executive ranks. As such, his departure sent shares tumbling 12 percent Wednesday.
The executive exodus "underscores a spate of challenges the company has faced as it squares off against Instagram and addresses ongoing challenges related to its app redesign," Cowen analyst John Blackledge said.
Snap, known for its disappearing photo and video messaging app, has been battling Facebook's Instagram for popularity. Instagram's Stories feature - which Facebook copied from a Snap feature with the same name - has 400 million daily users. Overall, Snap has 188 million daily active users - not just those on Stories.
Snap announced in late 2017 that it would redesign its app to attract more users, but existing users roundly despised the changes. Among other things, Snap tried to separate what friends share and what media organizations publish. After complaints, CEO Evan Spiegel said in May that the company would reverse some of the changes. So far, though, this hasn't stemmed the user decline.
Wedbush analyst Michael Pachter said he is "troubled" by Stone's departure. If Stone is leaving "because of an inability to mesh with other management," Pachter said, that could be a bad sign.
In announcing the departure Tuesday, Snap said there have been no disagreements with Stone about accounting, management, operations, regulatory matters or other issues.
In November, Snap disclosed that it has received federal subpoenas related to a class-action lawsuit stemming from its 2017 initial public offering. The lawsuit claims that Snap misled investors about its user growth before going public. The Santa Monica, California, company suggested at the time that regulators are looking into disclosures during its IPO about competition from Instagram.
