Nabi Biopharmaceuticals Initiates New Strategic Alternatives Process

ROCKVILLE, Md., Jan. 22, 2008 -- Nabi Biopharmaceuticals announced today that its Board of Directors has authorized the exploration of the full range of strategic alternatives available to the company in order to further enhance shareholder value. This strategic alternatives process will focus on, but is not limited to, a sale or merger of the company. Nabi has engaged Banc of America Securities LLC as financial advisor for this strategic process.

"The primary goal of this strategic alternatives process is to maximize shareholder value and we feel Nabi is now streamlined and well-positioned to do so,'' said Dr. Raafat Fahim, newly-named President and Chief Executive Officer of Nabi. ``With the sale of our Biologics business unit, Nabi has a very strong financial position, a focused pipeline of vaccine programs and a right-sized and lean organization. We believe that this strategic alternatives process can more fully optimize the value of our most promising assets, namely NicVAX(r) (Nicotine Conjugate Vaccine) and StaphVAX(r) (Staphylococcus aureus Vaccine).''

The successful outcome of this strategic alternatives process is the key corporate goal for this year. While advancing toward this goal, Nabi is also working to achieve several clinical milestones in 2008:

 * Initiating a Phase 2 immunogenicity study for NicVAX(r) in 1H08
 * Initiating a Phase 3 safety and efficacy trial for NicVAX(r) in 2H08
 * Advancing the development of the new antigens of Nabi's pentavalent
   StaphVAX program, enabling the initiation of Phase 1 clinical trials
   in early 2009

Following the successful sale of its Biologics Strategic Business Unit in December 2007, Nabi has re-emerged with a strong balance sheet, a significant potential PhosLo milestone and royalty stream, and a focused vaccine pipeline. The company is moving forward with compelling Phase 2 proof of concept clinical data from its NicVAX program and an expert core vaccine team. Dr. Raafat Fahim, President and CEO of Nabi, will discuss this strategic alternatives process, the company's 2008 goals and its plan to achieve them on a conference call. More information about this call is outlined below.

Upon completion of this strategic alternatives process, Nabi will inform shareholders of the results. The company does not intend to disclose developments with respect to the exploration of strategic alternatives unless and until its Board of Directors has made a decision regarding a specific transaction and a definitive agreement has been executed.
