Albertsons said Kroger has failed to make best efforts to secure regulatory approval of the deal, a claim the latter called “baseless.”

A federal judge blocked the deal and sided with the Federal Trade Commission, which raised antitrust concerns over the merger.

Albertsons and Kroger terminated their $25 billion merger plan on Wednesday after courts blocked the deal, with the former suing its rival and alleging a breach of contract that led to the deal's demise.
