SoftBank gets $7.6 bln T-Mobile stake windfall, shares soar

SoftBank Group Corp said it would receive shares in telco T-Mobile US worth some $7.59 billion at no additional cost, driving the Japanese conglomerate's shares up 5 per cent.

Masayoshi Son's conglomerate said late on Tuesday it had told T-Mobile US to issue 48.75 million shares in common stock to it after conditions set out in an agreement made as part of the merger of SoftBank's U.S. telco Sprint and T-Mobile were met.

The transaction bolsters the listed assets in SoftBank's portfolio, doubling its T-Mobile US stake to 7.64 per cent from 3.75 per cent currently, following the blockbuster listing of chip designer Arm in September.

"This increases the proportion of listed, measurable equity in hand on (SoftBank Group's) balance sheet, and, even better, proportions of marginal equity relative to indebtedness," Macquarie analyst Paul Golding wrote in a client note.

SoftBank's shares were on track for their biggest gain in more than a month. The conglomerate has risen only around 14 per cent year-to-date, compared with an almost 30 per cent rise in the benchmark index. The group trades at a discount of around 45.5 per cent to the value of its assets, according to Macquarie calculations.

Son has been a leading investor in late stage startups but has suffered a series of reversals including the bankruptcy of office-sharing firm WeWork, which was once the most valuable U.S. startup.

The T-Mobile US transaction bumps SoftBank's internal rate of return (IRR) on its Sprint investment to 25.5 per cent.

Other positives for the company include the recent rally in Arm's shares, which closed on Tuesday around 44 per cent above the initial public offering price.
