Biota, Inc. Announces Half Year Net Profit of AU$5.5 Million

Melbourne, Australia — 20 February 2008: Biota Holdings Limited (ASX: BTA) today announced a half year net profit after tax of AU$5.5 million, (1H F07: AU$4.1 million), a 35% improvement over first half F2007. Profit before tax was AU$7.5 million (1H F07: AU$4.1 million), up 83%. The result was driven by Relenza royalty revenues and growing collaboration income. Biota continues to achieve excellent progress on all of its drug development programs.

Total revenues were AU$30.4 million, up from AU$20.4 million in the comparable period last year, up 49%. Relenza royalties were AU$16.5 million (1H F07: AU$12.7 million) principally from sales of influenza pandemic stockpiling orders on GlaxoSmithKline (GSK). Collaboration income increased significantly to AU$9.6 million (1H F07: AU$5.9 million) reflecting activities from licensing agreements with MedImmune Inc. and more recently from Boehringer Ingelheim.

The Company also intends to undertake an on-market share buy-back of up to 5% of the issued ordinary shares, as part of its ongoing capital management strategy. The share buy-back will commence in approximately two weeks, following the normal regulatory notification process.

Commenting on the announcement today, Biota CEO Peter Cook said “This is a pleasing half year result and gives us the flexibility to extend our pipeline or progress existing programs further into clinic. In delivering major milestones under our licensed programs, we have been able to secure a significant added revenue stream to complement our Relenza royalty income”.

Total expenses of AU$22.9 million (1H F07: AU$16.3 million) reflect the costs associated with increased activity in both clinical and preclinical programs, some of which were reimbursed by licensees.

Expenditure associated with the litigation against GSK was AU$8.6 million (1H F07: AU$3.4 million) and reflects the preparation for trial, scheduled to commence on 4 August 2008.

Mr Cook added “The Supreme Court of Victoria has set a trial commencement date of 4 August 2008 and also has referred the matter to mediation to be completed by 31 July 2008. We remain firm in our commitment”.
