The shares are not gone- you just need to register under the US exchange. Email: Shareholder Services Department at
They will get you to fill in a W8BEN form which can be downloaded from a google search - fill in Parts 1 to 4 & dont worry about the reference number. Given we dont have an AST number or any shareholder reference number I am going to enclose a note with the form to explain the situation. I have had several emails back and forth to get this info so wanted to share it to save other the trouble

My 360 shares gone, no notification, no explanation. How do i recover these?
29/07/2014 20:51:55
This is the link to email them:

I am not happy with how this has been handled either. Link Market Services were unhelpful- I am trying to recover my share too as I was not notified either. They said the share registry for BOTA US is American Stock Transfer & Trust Co. I have just emailed them to explain the situation and find out where my shares are!10/07/2014 11:36:33
These comments are great but where do we find the answer. Is this an ICAC thing. I too cannot locate my original 2900 shares. Come on Biota send us confirmation of our shares.04/06/2014 13:38:47
I believe we are entitled to American Biota shares, how do we get confirmation of this17/03/2014 20:22:54
I own 4500 shares of BTA.  Noticed that the share is no longer shown in my broker account. Where all these share go, how I can get them back (either as cash or share certificate?)
03/03/2014 15:47:59
Who do you need to contact in the US. I am in the same situation, NOT HAPPY and do not know how to recover investment17/12/2013 15:47:11
I had 3700 shares and was not notified either re the takeover NOT HAPPY no one to discuss the matter at Biota Melb was told I had to callUSA at my expense.30/11/2013 17:23:52
What is market price of the Biota Shares on the Implementation Date ( 09/11/2012 ). Thank you . 05/09/2013 16:45:45
I could not agree more with the previous comment regarding how Biota (Australian) went about the "arrangement" with the American company prior to consulting the shareholder. So far ( July 2013 ) I have received no information regarding my shares.28/07/2013 21:57:02

It is most unfortunate that Aust. investment in Biota Holdings Ltd has enabled them to enter a Scheme of Arrangement per 11/2012 without the opportunity for shareholders to sell their shares before they are 'wiped' off  Although am not a large investor my little 300 shares now show 0 & has been delisted

on ASX with no information as to how to make contact with new proprietors  Very disappointing
