Kroger and Albertsons hope to merge but must face a skeptical US government in court first

The largest proposed grocery store merger in U.S. history is going to court.

On one side are supermarket chains Kroger and Albertsons, which say their planned merger will help them compete against rivals like Costco. On the other side are antitrust regulators from the Federal Trade Commission, who say the merger would eliminate competition and raise grocery prices in a time of already high food price inflation.

Starting Monday, a federal district court judge in Portland, Oregon, will consider both sides and decide whether to grant the FTC’s request for a preliminary injunction. An injunction would delay the merger while the FTC conducts an in-house case against the deal before an administrative law judge.

Kroger, based in Cincinnati, Ohio, operates 2,800 stores in 35 states, including brands like Ralphs, Smith’s and Harris Teeter. Albertsons, based in Boise, Idaho, operates 2,273 stores in 34 states, including brands like Safeway, Jewel Osco and Shaw’s. Together, the companies employ around 710,000 people.
