LANI Influenza Program Advancing Toward Phase 2 Clinical Development

Merger between Nabi Biopharmaceuticals and Biota Holdings Limited Successfully Completed

Biota Pharmaceuticals, Inc. (NASDAQ: BOTA) today announced its financial results for the three month period ended December 31, 2012 and recent corporate developments. The Company's fiscal year end is June 30.

"We are pleased with the progress of the LANI program such that we anticipate initiating a large, global Phase 2 clinical trial in patients with influenza in mid-2013," stated Russell H. Plumb, President and CEO of Biota Pharmaceuticals, Inc. "With the merger behind us and our balance sheet strengthened with the related net cash proceeds, we are now focused on integrating operations and completing an in-depth strategic, operational and financial review of our development programs, which we expect to complete by the end of this quarter."

Recent Corporate Developments

Merger between Nabi Biopharmaceuticals and Biota Holdings Limited - On November 8, 2012, the Company announced the completion of the merger between Nabi and Biota Holdings Limited, resulting in the formation of Biota Pharmaceuticals, Inc. Former Biota Holdings Limited shareholders retained approximately 83% of the Company's shares of common stock, while former Nabi shareholders retained approximately 17% as consideration for Nabi's net assets, which consisted primarily of $27 million in net cash on the date of the merger. The merger has been accounted for as a reverse merger, such that Biota Holdings Limited is considered the accounting acquirer for financial reporting purposes even though Nabi was the legal acquirer.

Reverse Stock Split - Concurrent with the completion of the merger, a reverse stock split of Nabi common stock occurred, resulting in each six shares of Nabi common stock issued and outstanding immediately prior to the reverse split being automatically combined into one share of Nabi common stock. As a result of the reverse split, the per share exercise price of, and the number of shares of common stock underlying all stock options outstanding immediately prior to the reverse split were automatically proportionally adjusted based on the 1:6 ratio in accordance with the terms of such options.

Laninamivir Octanoate (LANI) - Laninamivir octanoate is marketed in Japan by Daiichi Sankyo as Inavir® for the treatment of influenza A and B in adults and children. In November 2012, Daiichi Sankyo submitted an application for a label change in Japan to manufacture and market the influenza antiviral product Inavir® for the prevention of influenza A and B.

Under the contract the Company has with the U.S. Office of Biomedical Advanced Research and Development Authority ("BARDA"), in January 2013 the Company initiated a Phase 1 clinical trial designed to assess the pharmacokinetics and metabolite profile of laninamivir octanoate following an inhaled dose administered via TwinCaps®. This study is a single center, single dose, open-label study in six healthy male subjects. The Company anticipates that top-line results from this study will be available in mid-2013. Further, the Company anticipates initiating a 636-patient, randomized, placebo-controlled Phase 2 clinical trial of laninamivir octanoate in mid-2013. The primary objective of the study is to evaluate the safety and efficacy of two doses of inhaled laninamivir octanoate (40 and 80 mg) delivered via TwinCaps® in adults with symptomatic presumptive influenza A or B infection. The primary endpoint for this study is time to alleviation of influenza symptoms and fever for ≥ 24 hours.

Executive Management Changes - In connection with the merger, on November 14, 2012, the Company announced the appointment of Russell H. Plumb as its President and Chief Executive Officer, as well as a director, and Joseph M. Patti, M.S.P.H., Ph.D. as its Executive Vice President, Corporate Development & Strategy. Peter Cook, who resigned as the Chief Executive Officer of Biota Holdings Limited upon the completion of the merger, continues to serve as a director.

Mr. Plumb previously served as President, Chief Executive Officer and Chief Financial Officer of Inhibitex, Inc., a publicly-traded clinical-stage drug development company, from December 2006 through February 2012, when it was acquired. From 2000 to December 2006, Mr. Plumb was the Chief Financial Officer of Inhibitex.

Dr. Patti was a co-founder of Inhibitex, and served as its Chief Scientific Officer and Senior Vice President of Research and Development from 2007 through February 2012. Prior to that, he served as the Vice President, Research and Development and Chief Scientific Officer from 2005 to 2007 and Vice President of Preclinical Development from 1998 to 2005.

Financial Results for the Three Month Period Ended December 31, 2012

As of December 31, 2012, the Company held $74.1 million in cash and cash equivalents.

The Company reported net income in the three month period ended December 31, 2012 of $4.8 million, as compared to a net loss of $7.0 million in the second quarter of 2011. The $11.8 million change from net loss in 2011 to net income in 2012 was primarily the result of an $8.2 million increase in revenue, the recording of a $7.8 million gain related to the merger, and the receipt of a $4.4 million research and development credit, offset in part by a $7.7 million increase in total operating expenses, a $0.4 million decrease in interest income and a $0.5 million decrease in income tax benefits. Basic and diluted net income per share were $0.17 for the three month period ended December 31, 2012, as compared to a net basic and diluted loss per share of $0.31 in the same period of 2011.

Revenue increased to $10.4 million for the three months ended December 31, 2012 from $2.1 million in the same period of 2011, primarily as a result of increased service revenue in 2012 due principally to the advancement of the laninamivir octanoate program under the BARDA contract and higher royalty revenue.

Cost of revenue increased to $7.1 million in the three months ended December 31, 2012 from $2.9 million in the same three month period in 2011 due principally to the advancement of the laninamivir octanoate program under the BARDA contract.

Research and development expense decreased to $4.0 million in the second quarter of 2012 from $5.7 million in the second quarter of 2011, due largely to the completion of the vapendavir Phase 2 clinical trial during the quarter ended June 30, 2012, as well as lower preclinical costs associated with our antibacterial and hepatitis C virus programs and lower personnel-related and other indirect costs in general.

General and administrative expense increase to $7.1 million in the second quarter of 2012 as compared to $1.9 million in the second quarter of 2011 primarily due to merger-related costs of $3.3 million in 2012, an increase in salaries, benefits, stock-based compensation and recruiting costs related to the addition of executive and administrative staff in the U.S., as well as generally higher insurance, rent, and maintenance costs.

About Influenza and Laninamivir Octanoate

Influenza is a contagious and potentially fatal disease caused by a virus which infects the respiratory tract. Influenza viruses replicate in the cells lining the airways of the lungs and are generally spread directly to and from the respiratory tract by coughing and sneezing. Influenza can seriously affect anyone, but the people at highest risk of severe disease include young children, adults older than 65, and people of any age with underlying medical conditions, such as chronic heart, lung, kidney, liver, blood or metabolic diseases (for example, diabetes), or weakened immune systems.

Influenza spreads rapidly around the world in seasonal epidemics affecting between 5-15% of the population each year. According to the Centers for Disease Control and Prevention, in the U.S. alone, more than 200,000 people are hospitalized on average every year with influenza complications, and about 36,000 people die due to the disease. The World Health Organization estimates that annual epidemics around the world cause between three and five million cases of severe influenza, resulting in between 250,000 and 500,000 deaths every year.

The Company has developed first and second generation neuraminidase inhibitors, the first of which is zanamivir, which is marketed as Relenza® by GlaxoSmithKline. The Company's second generation neuraminidase inhibitors are referred to as long-acting neuraminidase inhibitors (LANIs) and are being evaluated as a once-weekly or once-only inhaled dose as compared to five day, twice-daily dosing needed with first generation neuraminidase inhibitors. The Company and Daiichi Sankyo co-own the rights for the development and commercialization of LANIs. The lead LANI, known as laninamivir octanoate, has completed clinical development in Japan and is marketed by Daiichi Sankyo as Inavir®.

In 2011, the Company announced it had been awarded a contract from BARDA for up to $231 million designed to support the clinical development and U.S. based manufacturing for laninamivir octanoate for the treatment of influenza A and B infections.

About Human Rhinovirus and Vapendavir

Human rhinoviruses (HRV) are a member of a large family of small viruses known as picornaviruses which are responsible for human diseases ranging from mild respiratory tract infections (the common cold) to paralytic poliomyelitis. HRV are the most commonly isolated viruses from people with mild upper respiratory tract illness. HRV can be a much more serious problem for some segments of the population such as infants and the frail elderly. HRV is a major cause of hospitalization for patients with underlying respiratory conditions, such as asthma, chronic obstructive pulmonary disease (COPD) and cystic fibrosis, where HRV can aggravate their existing disease. Estimates suggest that HRV is linked to about 70% of all asthma exacerbations and more than 50% of the hospitalized cases. Studies also suggest that more than 35% of acute COPD patients requiring hospitalization are associated with respiratory viruses, including rhinovirus.

The Company is developing vapendavir, a potent oral broad spectrum inhibitor of HRVs for the treatment of human rhinovirus infections and the reduction of exacerbations in patients with moderate to severe asthma or COPD. Vapendavir binds to the capsid of the HRVs and effectively stops the infection by interfering with the early steps in the infectious cycle. In March 2012, the Company announced that it had successfully completed a Phase 2b study in asthmatics with naturally acquired HRV infection.
