Overall I am pretty bullish about this company. But I think it is worth noting that as per todays investor presentation 61% of the companies revenue last year was generated in North America. With the AU$ trading at a ten year low should the AU$ appreciate or the US$ depreciate this poses a significant forex risk over the long term (presuming they have not hedged their rate at the current rate). Although Australia has good relations with the US there is a slight soveregin risk given Trumps "trade war", and his propensity towards tarrifs. It is a long shot and would be political suicide to tarrif medical goods but he never seems to stop supprising me.
I think the demand for medical supplies is failry inelastic though, and genral ecconomic changes should not effect long term demand.
I have attached the presentation from the ASX website if anyone is interested.
