Got the merger agreement in the mail last night. Someone correct me if I'm wrong, but this is how I read the transaction:
NK shareholders will get 1 share of IBRX for every 0.819 of their shares. This means that we get 1/.819 = 1.221 shares of IBRX for each NK share. But, the new IBRX shares are only 72% of the outstanding shares. Lokks like future dilution is coming.
