The simplest explanation is usually the correct one: LWLG hasn't announced any catalysts because they have nothing to announce.
Their technology is not ready for prime time. They have no named customers. They have no revenue.
None of this is in question. It is a simple fact.
Since they have no catalysts to announce, LWLG is adopting a "fake it till you make it approach", and hoping they can get enough gullible shareholders to give them just one more year.... just one more year..........just one more year...........just one more year.............
