SoftBank Corp. President Masayoshi Son said he’ll start a “massive price war” in the U.S. if regulators let his Sprint Corp. purchase T-Mobile US Inc.
The billionaire, who bought control of the third-largest wireless carrier last year, said combining with fourth-ranked T-Mobile would give him scale to compete against AT&T Inc. and Verizon Communications Inc. Those operators collect most of the U.S. mobile industry’s cash flow and don’t face “real competition,” Son said in an interview with PBS’s Charlie Rose.
