Kroger and Albertsons have amended their asset sale agreement with C&S Wholesale Grocers, increasing the number of stores to be divested to 579 for $2.9 billion in an effort to gain regulatory approval for their proposed $25 billion merger. The divestiture includes selling 166 additional stores, with specific adjustments in markets where the two companies overlap, such as selling 20 more stores in Illinois and details about the Nevada store, to address antitrust concerns. This strategic move aims to make the merger more appealing to federal antitrust regulators.
