Nabi Biopharmaceuticals Announces Share Repurchase Program

ROCKVILLE, Md., Dec. 6 /PRNewswire-FirstCall/ -- Nabi Biopharmaceuticals (Nasdaq: NABI) announced today that its Board of Directors has approved the repurchase of up to $65 million of the Company's outstanding common shares in the open market or in privately negotiated transactions. This share repurchase program includes the $3.1 million outstanding balance from the $5 million share repurchase program that the company announced in 2001.

"This repurchase program is the right thing to do for our shareholders and this is the right time to do it," said Dr. Leslie Hudson, Interim President and Chief Executive Officer of Nabi. "This is a first step. It not only reflects our continuing commitment to maximize shareholder value but also demonstrates our confidence in the value of Nabi's assets after closing the sale of our biologics strategic business unit. We will now shift our primary focus to the various alternatives that we may pursue to maximize the return of value to our shareholders from our considerable remaining assets -- which include our NicVAX(R) (Nicotine Conjugate Vaccine) and StaphVAX(R) (Staphylococcus aureus Polysaccharide Conjugate Vaccine) clinical programs, potential PhosLo milestones and royalties, as well as our significant net cash position. These future alternatives may include, but are not limited to, licensing or development arrangements; joint ventures or strategic alliances; the sale or merger of all or part of the company; and additional share repurchase programs or other distributions to our shareholders."
