Snap shares plummeted more than 11 percent in premarket trading Wednesday following the company's announcement Tuesday that its chief financial officer is resigning after less than a year on the job.

Snap disclosed CFO Tim Stone's resignation in an SEC filing Tuesday, saying he "has confirmed that this transition is not related to any disagreement with us on any matter relating to our accounting, strategy, management, operations, policies, regulatory matters, or practices (financial or otherwise)."
