Investment giant Softbank Group on Wednesday reported annual net profit of $45.8 billion, the best ever for a Japanese company, reaping the rewards of tech share rallies to recover from last year's record loss.

The telecoms firm turned investment behemoth has poured money into some of Silicon Valley's biggest names and hottest new ventures, from AI to biotech, through its $100-billion Vision Fund.
