It's effectively an earnings surprise. So the market will absolutely slam it for this. its credibility is damaged until it can string together enough consecutive months on target with revised plan. once debt cleared it will also improve, but big earnings shock when trying to pay down debt is very bad.
imagine a bank being 30% down on forecast revenue and 36% up on costs.
saying all that - I've moved to buy because we know a company generating US$120m a year in FCF would should be valued at au$1bn or more (P:E of 5 or 6 to 1).
