FOR IMMEDIATE RELEASE

Nabi Biopharmaceuticals Announces Fourth Quarter and Full-Year

2006 Financial Results

BOCA RATON, Fla., March 12, 2007 - Nabi Biopharmaceuticals (Nasdaq: NABI) today announced financial results for the fourth quarter and the full-year ended December 30, 2006.

For the full-year ended 2006, the company recorded a net loss of $58.7 million or $0.96 per share, compared to a net loss of $128.4 million or $2.15 per share in 2005. The 2005 net loss included a $27.4 million write-down or $0.46 per share related to our Gram-positive development program.

Revenues for the full-year 2006 were $89.9 million, compared with $94.1 million in 2005. Revenues in 2005 included $6.2 million of sales of WinRho SDF^® [Rh_o (D) Immune Globulin Intravenous (Human)] which the company stopped selling during 2005. Revenues for both years excluded sales of PhosLo^® (calcium acetate) which are included in discontinued operations. Revenues for the fourth quarter of 2006 were $30.3 million, 54% higher than the $19.6 million in the third quarter of 2006, reflecting strong sales of Nabi-HB^® [Hepatitis B Immune Globulin (Human)], which totaled $11.5 million, a $4.5 million arbitration award related to Inhibitex, Inc., as well as continued strength in the sales of antibody products.

During 2006, cash used by operations was $43.9 million, compared with $89.7 million used in 2005. The company’s cash equivalents and marketable securities at year-end 2006 were $118.7 million.

Leslie Hudson, Ph.D., interim president and chief executive officer, Nabi Biopharmaceuticals, stated, “We achieved a number of important milestones in 2006, including a marked improvement in the cash position of the company through the sale of PhosLo and a reduction in the company’s cost structure. We advanced our pipeline of promising product candidates and acquired the rights to ATG-Fresenius S a valuable addition to our transplant franchise. As a result, we enter 2007 with an improved operational and financial position.”

2007 Strategic Plan

Nabi Biopharmaceuticals also announced today that the company intends to re-organize its current operations into two strategic business units: Nabi Biologics and Nabi Pharmaceuticals. This will provide business clarity to the investment community, improve operating and financial performance and facilitate successful completion of Nabi’s strategic alternatives process, including but not limited to our work with Banc of America Securities. Under this new structure the company will further reduce its cost structure and cash burn in 2007.

Nabi Biologics will have responsibility for the company’s protein and immunological products and development pipeline, including Nabi-HB. The unit will manage the operations of the company’s plasma collection centers and protein fractionation and vaccine production plant.

The financial goal for the unit is to realize full value at each level of operation from plasma sales through to product revenue.

Our plans to further drive revenues, profits and cash flow include:

- Actively manage the life cycle of our product Nabi-HB, which provides antibody-based passive protection following exposure to hepatitis B virus. We will continue working with the FDA to secure approval for Nabi-HB Intravenous for the prevention of hepatitis B (HBV) re-infection after liver transplant.

- Secure regulatory approval for Civacir^® [Hepatitis C Immune Globulin (Human)], a polyclonal antibody product candidate for the prevention of the recurrence of hepatitis C virus (HCV)-related liver disease in HCV-positive liver transplant recipients.

- Secure regulatory approval for ATG-Fresenius S in the U.S., an immunosuppressive polyclonal antibody which is already marketed in Europe for the prevention and treatment of acute rejection following organ transplantation.

Nabi Pharmaceuticals will have responsibility for our NicVAX^® (Nicotine Conjugate Vaccine) and StaphVAX^® (Staphylococcus aureus Polysaccharide Conjugate Vaccine) programs, as well as the product Aloprim™ (allopurnol sodium) for Injection and our continuing milestone-related clinical development obligations following the sale of PhosLo.

The unit’s key business objectives are to:

- Complete the on-going Phase IIB “proof-of-concept” trial for NicVAX vaccine and secure a partner to further develop and market the product.

- Complete the on-going preclinical program for our new pentavalent StaphVAX vaccine and attract a strategic partner for its development and commercialization.

- Fulfill our milestone-related clinical obligations to our partner Fresenius following the sale of PhosLo.

- Sell our product Aloprim, which no longer has strategic importance for the business.

Leslie Hudson, Ph.D., interim president and chief executive officer, Nabi Biopharmaceuticals, stated, “The Board of Directors and new management team have put our new strategy into place to more rapidly and effectively unlock the true value of the company’s assets and to give both businesses a competitive advantage. We believe that this strategy will enhance the on-going strategic alternatives process, clarify our business and operating strengths and enable a range of outcomes including significant redirection of our business and the possible sale of part or all of the company.

As CEO, my role, with the senior management team, is to continue to lead Nabi Biopharmaceuticals overall and to successfully execute this plan. In this context, the 2007 goals for the corporation are to:

• successfully complete the strategic alternatives process

• obtain approval for Nabi-HB Intravenous in the U.S.

• announce Phase IIB trial results for NicVAX
