why stock price tanking??

Hi all, is anyone able to explain why after an announcement of a new 1 billion dollar contract plus the agl ann the SP continues to drop. it doesnt make sense. i understand holders dumping before the end of finacial year but this is ridiculas. does someone know something that we dont. from 2.95 to 2.22 in less than 3 weeks????? what is going on?????

i understand a similar question has been posted but we are yet to recieve a logical and informative answer.

thanks in advance
