TOKYO -- The completed merger between T-Mobile and Sprint lets Japan's SoftBank Group shrug off its struggling U.S. telecom business, but the tech investment company faces an even tougher challenge in the financial market turmoil sparked by the new coronavirus.
SoftBank held an 84% stake in Sprint, the No. 4 wireless carrier in the U.S. The deal with third-ranked T-Mobile diminishes SoftBank's influence, leaving the Japanese company with only a 24% stake in post-merger T-Mobile US.
