Momenta Pharmaceuticals Reports Financial Results for Second Quarter 2004

CAMBRIDGE, Mass., Aug. 16 /PRNewswire-FirstCall/ -- Momenta Pharmaceuticals, Inc. (Nasdaq: MNTA), a biotechnology company developing drugs based on sugar sequencing technology, today announced its financial results for the quarter ended June 30, 2004. The Company reported a net loss of $2.9 million for the quarter ended June 30, 2004 compared with a net loss of $1.8 million for the same period in 2003. The Company's net loss for the six months ended June 30, 2004 was $5.5 million compared with a net loss of $3.3 million for the same period in 2003. Net loss attributable to common stockholders for the three and six month periods ended June 30, 2004 was $3.9 million, or $0.79 per share, and $27.7 million, or $7.28 per share, respectively. Net loss attributable to common stockholders for the same periods in the prior year was $2.1 million, or $1.14 per share, and $3.8 million, or $2.27 per share, respectively.

At June 30, 2004, the Company held cash, cash equivalents, and short-term investments of approximately $64.0 million compared with $12.6 million as of December 31, 2003. The growth in cash balances reflects net proceeds of $20.4 million from the sale of Series C redeemable convertible preferred stock in February 2004, and net proceeds of $35.3 million from Momenta's initial public offering of common stock which was completed on June 25, 2004.

"We believe our recent financings will enable us to advance our near-term product opportunities including M-Enoxaparin, a technology-enabled generic version of Lovenox®, as well as our discovery and development programs in cardiovascular medicine, non-invasive drug delivery and oncology," commented Alan Crane, Chairman and Chief Executive Officer. "We continue to execute on our plan to leverage our innovative technology and unique ability to sequence complex sugars to create value from existing drugs and develop novel drugs for critical diseases."

The Company reported revenues under its collaborative agreement with Sandoz, an affiliate of Novartis AG, of $2.1 million for the quarter ended June 30, 2004 and $3.2 million for the six months ended June 30, 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 no collaboration revenue in 2003.

Research and development expenses for the quarter ended June 30, 2004 were $3.5 million, compared to $0.9 million for the same period in 2003, while research and development expenses for the six months ended June 30, 2004 increased to $5.7 million compared to $1.7 million for the same period in the prior year. The increase in research and development spending was primarily due to increased expenses associated with the M-Enoxaparin program and with the development of M118, a novel low molecular weight heparin for acute coronary syndromes. In addition, research and development spending reflects Momenta's overall growth and increased headcount associated with the advancement of programs such as non-invasive drug delivery and oncology.

General and administrative expenses for the quarter ended June 30, 2004 totaled $1.6 million, compared with $0.9 million for the same period in 2003. General and administrative expenses for the six months ended June 30, 2004 were $3.0 million, compared with $1.6 million for the same period in 2003. The increase in general and administrative spending was primarily due to an increase in stock compensation expense, increased personnel and related costs as a result of increased headcount, and increased professional fees.
