TOKYO—Japanese technology investor SoftBank Group Corp. reported a record quarterly loss of more than $23 billion after an investment spree that Chief Executive Masayoshi Son described as delirious turned sour.
The April-June loss, triggered by a global selloff in technology shares, was about 1½ times the previous record set just three months earlier in the January-March quarter. Mr. Son said job cuts and asset sales were planned as part of a retrenchment.
