Momenta Pharmaceuticals Reports Financial Results for the Fourth Quarter and Fiscal Year 2004

CAMBRIDGE, Mass., Feb. 10 /PRNewswire-FirstCall/ -- Momenta Pharmaceuticals, Inc. (Nasdaq: MNTA), a biotechnology company developing drugs based on its proprietary sugar sequencing technology, today announced its financial results for the fourth quarter and fiscal year ended December 31, 2004.

For the fourth quarter 2004, the Company reported a net loss of $4.3 million compared with a net loss of $2.3 million for the same period last year. The Company's net loss for the fiscal year 2004 was $14.1 million compared with a net loss of $7.9 million for the prior year.

Net loss attributable to common stockholders for the fourth quarter 2004 was $4.3 million, or $0.18 per share compared with $3.0 million or $1.25 per share for the fourth quarter 2003. Net loss attributable to common stockholders for fiscal year 2004 was $36.3 million, or $2.56 per share compared to $9.8 million, or $5.02 per share, for the fiscal year 2003. Net loss attributable to common shareholders includes the impact of the deemed dividend related to beneficial conversion feature of Series C redeemable convertible preferred stock and dividends and accretion to redemption value of redeemable convertible preferred stock.

"We continue to move forward on our lead product, M-Enoxaparin, a technology enabled generic version of the low molecular weight heparin drug Lovenox®, and we expect to file the ANDA for M-Enoxaparin in mid-2005," commented Alan Crane, Chairman and Chief Executive Officer of Momenta. "We also continue our efforts in our programs for M-Dalteparin, a technology enabled generic version of the low molecular weight heparin drug Fragmin®, and M-118, the Company's preclinical novel low molecular weight heparin candidate targeted for acute coronary syndromes."

"We recently announced our 2005 goals for our glycoprotein program. During 2005, we intend to characterize the sugars on multiple glycoprotein drugs and establish a product partnership. By applying our proprietary sugar sequencing technology to glycosylated proteins, or proteins that contain complex sugars, we believe that we can broaden our product opportunities to include the $33 billion market for protein therapeutics. Most protein and antibody drugs are glycosylated and have not been well characterized. Glycosylation determines critical product properties, including efficacy, safety, specificity, half-life, and immunogenicity. We believe characterization of the sugars on these drugs could have significant implications for developing follow-on proteins and engineering improved drugs," continued Mr. Crane.

At December 31, 2004, the Company held cash, cash equivalents, and marketable securities of $55.1 million, including $1.5 million of restricted cash associated with a recent lease for its new headquarters, compared with $12.6 million as of December 31, 2003. The Company received net proceeds of $35.3 million from its initial public offering of common stock which was completed on June 25, 2004.

The Company reported revenue under its collaborative agreement with Sandoz, an affiliate of Novartis AG, of $2.8 million for the fourth quarter 2004 and $7.8 million for the fiscal year 2004. Under the collaboration, Momenta and Sandoz have agreed to jointly develop, manufacture, and commercialize M-Enoxaparin, and Sandoz is responsible for funding substantially all of the development, regulatory, legal and commercialization costs associated with M-Enoxaparin. The Company reported collaborative revenue of $1.5 million for the fourth quarter and fiscal year 2003.

Research and development expenses for the fourth quarter 2004 were $5.5 million, compared to $2.2 million for the same period in 2003, while research and development expenses for the fiscal year 2004 were $15.7 million compared to $5.3 million for fiscal year 2003. The increases in research and development spending for both periods were primarily due to increased personnel and related costs as a result of increased headcount, increased expenses associated with the M-Enoxaparin program and increased stock compensation expense.

General and administrative expenses for the fourth quarter 2004 totaled $1.9 million, compared with $1.6 million for the same period in 2003. General and administrative expenses for the fiscal year 2004 were $6.8 million, compared with $4.1 million for the same period in 2003. The increases in general and administrative spending for both periods were primarily due to an increase in personnel and related costs as a result of increased headcount, additional insurance coverage and increased professional fees, and for the full year, an increase in stock compensation.
