I have made this point before but it looks like it needs made again - sportingbet is NOT rock solid financially or anything like it.
They have substantial payments to make under the earn-out terms of their many acquisitions and it is not certain they can meet these, though they have been making progress in recent months.
Having said that, the founder took the chance to raise €10m or so selling one third of his stake near the bottom of the market, not exactly a vote of confidence.
For US punters, it is important to realise that we do not have anything as robust as Chapter 11 in allowing companies to see off problems by carrying on trade. Most UK liquidations are run for the benefit of the Inland Revenue and the liquidator.
I have been involved - luckily with only $50 balances - in 2 of these, Luvbet and Netbetsports. In both cases the liquidator has reported that unsecured creditors like myself can expect nothing.
Should sportingbet plc go bust, I would expect a payout of between 0% and 5% of my balance at the time, probably 0%.
