Series C warrants are done, finished last year. Series A are still out there with a max os of 12.2mil not including their new deal with riverside
Do the math, they do not need to dilute. The deal with riverside did two things, saved them from paying principle (~500k) & dropped their coh requirement to 6.5mil. This will carry them till May where they can elect to have Riverside pick upto 2 mil more principle debt. This would drop the COH requirement to 5.5mil. All of this though was done to bide them time until they can refinance; which I assume is in the works based on the recent PR.
Riverside warrants are not exercisable for 6 months and the principle note does not convert until 2018 if Amedica doesn't pay them instead.
For now, no new dilution. Expect more warrants with any new loan and hopefully the terms will give them access to their current cash on hand.
