Difficult to say at this point, but the stalemate won't last.
Either AUT increases the bid, which may or may not work, or they withdraw next month, in which case they'll probably not be successful (unless there's a rush of buyers at the end, which I think it unlikely). Or they could withdraw early (which I believe is virtually 100% certain not to happen).
Most likely we'll see very little happen until a few days before the deadline, AUT will increase the offer, and from there we'll see some action. What will happen is very difficult to predict at this point. They're worth over a dollar. Assuming I'm right and the most likely scenario transpires (the offer is increased) if they get bought out you'll make a quick small profit by buying today, and if not you'll make a big profit in 6-24 months if you buy today.
A clear buy for now.
Also, a lot of people are talking about how far EKA would drop if the offer was removed, speculating low 20s. I disagree. If the offer had not been there at all, yes, low 20s, maybe back into the teens. However, AUT has clearly shown that it is worth far more than 45c. In the 20s we were a takeover target, sufficient to be actively hunted. That being the case, we're obviously a screaming buy at anything under 40c (I would say 60-70c), even without a takeover offer.
