Hi there,
Doesn't look all that attractive to be honest. Looks like it is a company that has traded sideways/downwards since 2004. Revenue has been highly inconsistent over the years and despite the fact that the lase industry is expected to grow by 8% annually, TLT hasn't proven its ability to grow with it.
The only consistency? High dilution. YoY the company's shares outstanding have trended outwards, likely because it doesn't generate sufficient revenue to operate so it needs to continuously issue shares and raise capital to move forward. Not surprising considered it has posted negative cash from operations since the beginning.
Not saying this company won't be successful moving forward, but I'd have to see a lot more from the company to be interested. I'd consider it to be one that is highly volatile and carries considerable risk.
