The Federal Trade Commission sued PepsiCo on Friday, alleging that it has engaged in illegal price discrimination by giving unfair price advantages to one large retailer at the expense of other vendors and consumers.

The Federal Trade Commission on Friday sued PepsiCo in a last-minute blitz of lawsuits before the end of the Biden administration, alleging that the beverage giant forced many consumers to pay higher prices by giving Walmart unfair pricing advantages.

The agency claims the soda giant gave “unfair” pricing advantages to a larger retailer, forcing consumers to pay more at competing stores. Pepsi “strongly disputes” the allegations.
