Are you here to trade SPT in and out or hold long term?
"APT and SPT is not the same as comparing WHA to A2M" - that's besides the point, some posters are supposedly basing a big part of their investment decision based on SPT being fraction X of APT. Hence why I gave an example of a speccy stock vs a volatile but much more established player in the same industry.
Well done to you for trading WHA and making a killing, golden star. Nearly anyone who bought into WHA in the last year though would have now lost money, up to 65% down.

On the note of company size,
SPT has a total of 327 million shares, options and performance rights. Fully diluted that makes this company valued at $327 million at $1.00 SP. It closed at $1.12, so we're looking at a fully diluted market cap of $366 mil or $346 mil if you leave out the performance rights.
On Warnie's numbers below you'd need $2 billion in sales to justify this. Last year they did $80 million in sales. I know chris here will pull up a screenshot of Afterpay's presentation, but SPT is not Afterpay. They are a different business, and as yet are untested. A huge amount has been priced in right now. Afterpay was about $500 mil market cap pre-merger in June 2017 and at that point had done $550 million sales in a year. In its current year it is forecast to do $5.2 billion and has roughly that as its market cap. Its net transaction margin will be about 1.85% (that's after bad debt, collection charges & interest costs). That's higher than the total revenue margin SPT it has, so it would be generous to say that SPT should also be market cap of its current annual run-rate like APT was. But if it was, SPT's run rate of $32 mil per quarter = $120 mil annualised. If $120 mil was the market cap, SPT's share price would be 35-40c depending on dilution assumptions. That's still a handy 100% return on IPO.
