...May 20, 2021 - Seven & i Holdings said on May 15, 2021, that its U.S. subsidiary 7-Eleven Inc. has completed the acquisition of convenience store and gas station chain Speedway LLC. - The holding company's credit quality has worsened materially because financing the deal entirely with debt substantially hurts its financial standing, despite the stronger business base resulting from the acquisition. - We lowered by two notches to 'A' the long-term issuer credit ratings on Seven & i, Seven-Eleven Japan Co. Ltd., and 7-Eleven Inc. and lowered by one notch to 'A-1' the short-term issuer credit rating on Seven-Eleven Japan. We also lowered our issue ratings on Seven & i and 7-Eleven, and we removed all of the ratings from CreditWatch negative. - The negative outlook reflects our view that there is at least a one-in-three chance of the benefits of integration with Speedway being delayed, resulting in slower debt reduction over the next one to two years than we assume.
