Sol IMO you would need to wait until a least the refinancing has been finalised.
The company has announced they are negotiating better terms with a new finance provider but the reality is it has not been completed.
Better to buy once you at least know this has been done. They are saying they have extended the payout of the con note until the end of March.
The other issue that you also should be looking at is the current mature businesses of the company have been losing market share and revenues have been falling at an alarming rate. If the new side of the business cannot offset the falling revenues by gaining strong sales then IMO they will need to raise more equity due to the current burn rate.
The company has indicated they have just signed up a major airline and working with other majors. Will revenues from these new customers offset the dwindling revenues from the other operations is the question to ask yourself.
