Pepsi sued by federal regulators for giving Walmart preferential soft-drink pricing

The Federal Trade Commission said Friday that it is suing PepsiCo for illegal price discrimination, alleging the food and beverage giant gave an unnamed retailer more favorable prices than its competition.

Walmart is the unnamed retailer, people familiar with the matter told CNBC.

The FTC alleges Pepsi violated the Robinson-Patman Act, which bars sellers from giving competing buyers different prices for the same “commodityâ€� or selectively providing allowances, like compensation for advertising. The agency argues Pepsi gave Walmart promotional payments and allowances, as well as advertising and promotional tools, that it didnâ€t offer to the retail giantâ€s rivals.

Pepsi denied the allegations and said the FTCâ€s lawsuit is wrong, both factually and legally.

“PepsiCo strongly disputes the FTCâ€s allegations, and the partisan manner in which the suit was filed. We will vigorously present our case in court,â€� the company said in a statement to CNBC. “PepsiCoâ€s practices are in line with industry norms and we do not favor certain customers by offering discounts or promotional support to some customers and not others.â€�

Walmart did not immediately respond to a request for comment from CNBC.

The complaint, which was filed in the Southern District of New York, is currently sealed.

The FTC also said that a “substantial portion� of the alleged violations are redacted in the lawsuit, citing legal protections given to Pepsi and the large, big box retailer. The commission is seeking to lift the redactions to show how Pepsi broke the law and how those alleged actions led to higher prices for competing retailers.

The Robinson-Patman Act was passed in 1936, but the federal government stopped enforcing it during the deregulation of the 1980s. The FTC resumed its enforcement in December when it sued Southern Glazerâ€s, the largest U.S. distributor of wine and spirits.

The lawsuit comes on the final business day before President-elect Donald Trumpâ€s inauguration on Monday, which will spell the end of Lina Khanâ€s time as chair of the FTC. Her Republican successor, Andrew Ferguson, currently serves on the commission and released a statement dissenting against the decision to sue Pepsi.

The Biden administration has taken a flurry of legal action against companies and corporate executives in its final days, targeting Capital One, Southwest Airlines and Elon Musk, among others.
