March 12, 2010— Novavax, Inc. announced financial results today for the fourth quarter and year ended December 31, 2009.

Novavax reported a net loss of $14 million, or $0.15 per share, for the fourth quarter of 2009 compared to a net loss of $11.1 million, or $0.16 per share, in the fourth quarter of 2008. For 2009, the company reported a net loss of $38.4 million, or $0.45 per share, compared to a net loss of $36 million, or $0.53 per share, for 2008. The primary reason for the increased loss in the comparative fourth quarter and year-over-year results are the number and size of the clinical trials that were performed in 2009, compared to 2008.

At December 31, 2009, Novavax had cash, cash equivalents and short-term investments of $43 million compared to $33.9 million at December 31, 2008. Working capital increased from $7.4 million in 2008 to $36.5 million in 2009.

Dr. Rahul Singhvi, President and Chief Executive Officer of Novavax, stated: "During 2009, Novavax made substantial progress across every part of our business and in each of our vaccine programs. We raised $56 million in new capital, launched a pivotal study of our 2009 H1N1 VLP pandemic influenza vaccine in Mexico with encouraging results to date, demonstrated safety and immunogenicity of our trivalent seasonal VLP influenza vaccine and identified a viable vaccine candidate to prevent respiratory syncytial virus (RSV). We have now conducted five human clinical studies for our pandemic and seasonal VLP vaccine candidates in over 4,200 subjects, demonstrating safety and immunogenicity. We plan to begin Phase III studies of our influenza vaccines, subject to the expected results of the ongoing Phase IIa trial in older subjects and future clinical pathway discussions with the FDA. The Company ended 2009 with a solid balance sheet and a strong scientific position that will enable us to continue to advance our pipeline products."
