TOKYO -- SoftBank Group plans to break off negotiations toward a merger between subsidiary Sprint and T-Mobile US amid a failure to come to terms on ownership of the combined entity, dashing the Japanese technology giant's hopes of reshaping the American wireless business.
SoftBank is expected to approach T-Mobile owner Deutsche Telekom as early as Tuesday to propose ending the talks. They had reached a broad agreement to integrate T-Mobile and Sprint -- the third- and fourth-largest carriers in the U.S. -- and were ironing out such details as the ownership ratio.
