I got in at $10.19 the day they announced the news. As for outstanding shares changing, yes I assume that will increase based on however many shares were issued to the seller of TPx Communications.
Forgot to add; They paid 95M in shares to TPx Sellers on top of the 248M Cash. This would add 9.5M to the current outstanding shares. The PIPE I believe is around 30M shares.. so I am estimating around 74M shares outstanding when the dust settles.
