GoPro Inc., marking its first debt offering since going public nearly three years ago, plans to sell  $150 million aggregate principal amount of convertible senior notes due 2022.

The proceeds of the offering would be used for general corporate purposes as well as a stock buyback. The convertible senior notes, which will be sold via a private placement, will mature in 2022.

GoPro repaid $114 million in debt in 2014, just before it went public, leaving it debt-free until now.
