In thinkiing about a buyout, people often fail to give some credit for the avoidance of further risk in a developmental stage company. However, after this long, and especially after the traction we seem to have gotten with the interposer, I would not want to see us go for less than a buck US, at a time we're under .40 US, or so. And I don't think management would support that type of buyout. It's rare that a company will offer more than twice the then current share value, but it could happen, especially if we're as near as we seem, with as good a product as it seems.
Now, if we get up to $1.50 US and sales are growing and feedback on performance of the product is good, then I could see an offer of $2.50 or $3.00 with a decent possibility of a bidding war, as we would still be cheap considering the potential. Such a war could easily see the stock get to over $4, and maybe over $5. Also, if sales and feedback are very good, well, the stock may rise all by itself very sharply.
This all could happen relatively soon (6-9 months). The gulf between .30 US and $5 US is not great in time, the gulf lies in terms of "we have a great product for sale" and "we don't." Once the share price starts moving due to sales of a perceived and proven great product, the share price should move fast. With some proper promotion, we could be talking 2 months time for a huge move. But, the above is only going to happen when our customers confirm that they like what they can see and feel.
