PepsiCo said Monday it’s acquiring the prebiotic soda brand Poppi for $1.95 billion. The acquisition gives PepsiCo a fast-growing brand in the popular functional beverage category.

PepsiCo Inc. will acquire healthier soda brand Poppi for $1.95 billion, the Purchase, New York-based soda giant announced on Monday, confirming an earlier Bloomberg News report. The deal includes $300 million in expected cash tax benefits for a net purchase price of $1.

Last year, several class-action lawsuits were filed against a prebiotic soda claiming the product didn’t improve gut health as much as advertised.
