- ------------------------------ --------------------- CUSIP NO. 629519109 SCHEDULE 13D PAGE 6 OF 11 PAGES - ------------------------------ --------------------- Item 1. SECURITY AND ISSUER This statement relates to the shares of common stock, par value $0.10 (the "Shares"), of Nabi Biopharmaceuticals (the "Issuer"). The principal executive office of the Issuer is located at 5800 Park of Commerce Boulevard N.W., Boca Raton, Florida 33487. ITEM 2. IDENTITY AND BACKGROUND (a) This statement is filed by Harvest Management, L.L.C. ("Harvest Management"), James Morgan Rutman, Nathaniel Bohrer and Marjorie Gochberg Kellner (collectively, the "Reporting Persons"). Harvest Management is filing this Schedule 13D with respect to the Shares beneficially owned by the following accounts under its management, which Harvest Management may be deemed to beneficially own: Harvest Capital, L.P., Harvest Offshore Investors Ltd., CL Harvest, LLC, Harvest AA Capital, L.P., New Americans, L.L.C. and TE Harvest Portfolio, Ltd (collectively, the "Holders"). James Morgan Rutman, Nathaniel Bohrer and Marjorie Gochberg Kellner are each principals of Harvest Management and thus may be deemed to beneficially own the Shares beneficially owned by Harvest Management. The Reporting Persons disclaim that they and/or the Holders are members of a group as defined in Regulation 13D-G. (b) The principal business address of the Reporting Persons is c/o Harvest Management, L.L.C., 600 Madison Avenue, 11th Floor, New York, New York 10022. (c) The principal business of Harvest Management is providing investment management services to accounts under their management. James Morgan Rutman, Nathaniel Bohrer and Marjorie Gochberg Kellner are each principals of Harvest Management. (d) None of the Reporting Persons has, during the last five years, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors). (e) None of the Reporting Persons has, during the last five years, been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. (f) Each of James Morgan Rutman, Nathaniel Bohrer and Marjorie Gochberg Kellner is a citizen of the United States of America. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. Funds for the purchase of the Shares reported herein were derived from the available capital of the Holders. A total of approximately $24,482,815 was paid to acquire such Shares.
- --------------------------- ------------------- CUSIP NO. 629519109 SCHEDULE 13D PAGE 7 OF 11 PAGES - --------------------------- ------------------- ITEM 4. PURPOSE OF TRANSACTION. The Reporting Persons previously filed a Schedule 13G with respect to the Shares on February 10, 2006. The Reporting Persons originally acquired the Shares for investment in the ordinary course of business because they believed that the Shares, when purchased, were undervalued and represented an attractive investment opportunity. On May 1, 2006, the Issuer sent a letter to another large shareholder stating that the Issuer's current management remains committed to attempting to execute its strategic plan for the next two years as opposed to considering other avenues to maximize shareholder value in the near term. The Reporting Persons believe that the current investment environment is extremely attractive for vaccine products and thus should greatly favor the Issuer. However, the Reporting Persons are concerned that the Issuer's current management and board of directors is not the best qualified to maximize the value of the scientific work of the Issuer's excellent research personnel. Specifically, the Issuer's current management has twice failed to successfully complete a pivotal confirmatory trial for StaphVax, and also has been unable to even secure European approvals for currently marketed products PhosLo and Nabi-HB, both of which were expected long ago. The Issuer's stock is now trading at approximately half of the level it traded ten years ago. Accordingly, the Reporting Persons believe that the significant intrinsic value of the Issuer's assets can be much better realized as part of a larger, more experienced organization. The Issuer's 2006 annual meeting of stockholders (the "Annual Meeting") is scheduled to be held on May 12, 2006. The Reporting Persons will not attend or vote the Shares at the Annual Meeting and intend to encourage certain other of the Issuer's shareholders to take similar actions in an effort to deny the presence of a quorum and force the Issuer to reschedule the Annual Meeting. The Reporting Persons believe, based on the Issuer's By-Laws, that should such rescheduling require the issuance of a new notice of meeting by the Issuer, then the Reporting Persons would be entitled to give notice to the Issuer of their intention to propose certain actions to be included on the agenda at the rescheduled Annual Meeting. If entitled to do so, the Reporting Persons currently intend to give such notice, which may include the nomination of persons to be elected to the Issuer's board of directors and/or propose other actions designed to seek to maximize shareholder value of the Issuer. Except as set forth herein or as would occur upon completion of any of the actions discussed herein the Reporting Persons have no present plan or proposal that would relate to or result in any of the matters set forth in subparagraphs (a)-(j) of Item 4 of Schedule 13D. The Reporting Persons intend to review their investment in the Issuer on a continuing basis and may engage in discussions with management, the Board, other shareholders of the Issuer and other relevant parties concerning the business, operations, board composition, management, strategy and future plans of the Issuer. Depending on various factors including, without limitation, the Issuer's financial position and strategic direction, the outcome of the discussions and actions referenced above, actions taken by the Board, price levels of the Shares, other investment opportunities available to the Reporting Persons, conditions in the securities market and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, purchasing additional Shares or selling some or all of their Shares, engaging in short selling of or any hedging or similar transactions with respect to the Shares and/or otherwise changing their intention with respect to any and all matters referred to in Item 4 of Schedule 13D.

(b) Each of the Reporting Persons have shared voting and dispositive powers over the 5,615,658 Shares.
