Todays reaction was expected, MRK priced in the aquisition way before it was announced
Deal is only for "30%" with an option to aquire more later on "at a cost"
494,894,020 shares on issue + 65mil 1 cent options, fully diluted 560,116,242
At 4 cents $20mil+ cap is fair in this market, early stage atm, but as they deliver more news will rerate accordingly
