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

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 announced Wednesday it is pulling out of its plans to merge with Kroger, citing two court rulings on Tuesday barring the transaction.
