It can mean a few things. They could be taking the company private but if there was an offer we'd know. They could be going broke but would have filed for bankruptcy first. Most likely they can't afford to be fully reporting after blowing all their cash so are going pink which doesn't mean much. They have a duty to release news to clarify but they're dumbasses. The only other possibility is to do with the toxic convertibles but since the don't release news I guess the shareholders have no right to know.
no tweets or facebook posts in over a month. Looks like they have given up or are closing doors. Don't know but that's what it implies to me.
My impression is this company couldn't figure out a way to get the market to want their technology, no matter how superior it might be. If the market doesn't want it, what good is it really?
