Thwarted by federal and state judges, Albertsons gave up on its proposed $24.6 billion sale to Kroger and sued its would-be merger partner.

The supermarket chain had tried to join forces with Kroger, but judges sided with federal and state regulators who charged that the merger would reduce competition.

Albertsons is giving up on its merger with Kroger a day after it was rejected in two courts and it is suing the chain, saying it didn’t do enough to secure regulatory approval of the $24.6B agreement.
