I think EIPC is just way below almost everyone's radar and was written off for dead a couple of years ago. They're just too tiny and the path to profitability is unclear. I've spoken with the CEO a few times and he seems like a smart guy, but they really need a contract award or government grant to get some credibility. Their little $10,000 potentiostat sales are not sufficient to create buying interest in a little Pink Sheet company.
I still think they're a decent Lotto play and continue to hold my shares.
