The Welsh singer will make five albums for Warner Music under a contract worth more than £5.8 million.
By signing the deal, Jenkins leaves former label Universal, but now believes she is better positioned to make an impact in the US.
"I'm very sad to be leaving Universal because that's where it all started ... but I've been offered an opportunity I can't refuse," she told the BBC.
Jenkins will now spend four months in Los Angeles to record her first album for Warner. Sacred Arias, her final record with Universal, is released on Monday.
