Simple. Once there are only 20 million shares and the share price is a healthy $5 or so, they'll issue and sell another 10 million to the market at $5. Instant capital. Instant liquidity. It's a great deal for the company and probably a smart move. If I was a shareholding employee, I'd be pleased right now. That's the majority of their shareholders and that's who they should be accountable to.
I fault the company for not being up front in their first PR about how the merger would be enacted. Honest mistake? Probably. It sucks, but what can you do? We didn't have to buy on incomplete information. That was our risk and now we have to pay.
