Two Major Independent Proxy Advisory Firms Recommend Nabi Biopharmaceutical Stockholders Support Amended Transaction With Biota Holdings Limited at October 22nd Reconvened Special Meeting

ROCKVILLE, Md., Oct. 16, 2012 (GLOBE NEWSWIRE) -- Nabi Biopharmaceuticals (Nadsaq:NABI) ("Nabi") today announced that the two major independent proxy advisory firms, Institutional Shareholder Services ("ISS") and Glass Lewis, have recommended that Nabi stockholders support the recently amended transaction agreement with Biota Holdings Limited (ASX:BTA.AX) ("Biota") pursuant to which Nabi would acquire all of the outstanding shares of Biota in exchange for shares of Nabi common stock (the "Transaction"). ISS and Glass Lewis are the leading independent proxy advisory firms and their voting analyses and recommendations are relied upon by hundreds of institutional investment funds, mutual funds and fiduciaries throughout the world.

In recommending that Nabi stockholders support the Transaction, ISS said:

"Given the values of the revised deal terms, a liquidation scenario no longer appears reasonably likely to provide shareholders with greater value than the acquisition by Biota. As such, shareholder support for the acquisition is warranted."*

Accordingly, ISS has recommended that Nabi stockholders vote "FOR" Proposal 1 (To Increase Nabi's Authorized Common Stock), "FOR" Proposal 2 (To Change the Name of Nabi), "FOR" Proposal 3 (To Effectuate a Reverse Stock Split), "FOR" Proposal 4 (Issuance of Nabi Shares in Connection with the Transaction) and "FOR" Proposal 6 (Adjournment of Special Meeting).

In its October 10, 2012 report Glass Lewis concluded:

"We continue to believe that the proposed merger with Biota has strategic merit. We now also believe that the valuation proposition is more balanced and fair to Nabi shareholders. Under the revised terms, the implied valuation for Nabi shareholders is significantly higher than under the original terms and also exceeds the amount estimated to be distributed in a liquidation scenario."*

Accordingly, Glass Lewis has recommended that Nabi stockholders vote "FOR" Proposal 1, "FOR" Proposal 2, "FOR" Proposal 3, "FOR" Proposal 4 and "FOR" Proposal 6.

Nabi stockholders are encouraged to read Nabi's Definitive Proxy Statement, dated August 7, 2012 and the Supplement to the Definitive Proxy Statement, dated September 25, 2012, in their entirety as they provide, among other things, a comprehensive discussion of the process that led to the Biota Transaction, important information about the Transaction and the reasons Nabi's board is recommending the Transaction to its stockholders.


Nabi urges stockholders to vote "FOR" each of the proposals today. Stockholders who have questions about the proposals or who need assistance voting their shares should contact the Company's proxy solicitor, Morrow & Co., LLC, toll-free at (800) 607-0088 or (203) 658-9400.

If stockholders previously voted a green proxy card or green voting instruction form, that vote will not be counted at the special meeting scheduled to reconvene on October 22, 2012. If stockholders previously submitted a white proxy card voting against the transaction, Nabi's Board of Directors urges such stockholders to revoke that vote and vote "FOR" each of the proposals to be considered at the reconvened special meeting. Only the latest dated proxy is counted. If a stockholder has already voted "FOR" the proposals on a white proxy card or white voting instruction form, the stockholder does not need to vote again.
