Ann: $10m Institutional Placement, page-25

@hotmix87 thank you for sharing that email, it provided alot of insights.
They mention that PayPal & Skrill (Paysafe) have no near-term plans to enter ISX's AML regulated target sector markets, and that the potential full market revenue is approx. $200m, of which ISX aims to grab 10% of this in the near term.
So the other 90% of the market would continued to be served by the Big4 banks. I haven't come across information on other competitors, would anyone know who they are?

And regarding the guidance announcement just before the CR, ASX disclosure rules means that ISX must release material information as soon as they've been made aware of it. If they had held back on this information and released it after the CR, I think ASX would have dropped the hammer on them (and not to mention the shareholder backlash).
