PENWEST REPORTS FIRST QUARTER 2005 FINANCIAL RESULTS
Danbury, CT, April 29, 2005— Penwest Pharmaceuticals Co. (NASDAQ: PPCO) today announced its financial results for the first quarter ended March 31, 2005.
Total revenues for the first quarter of 2005 were $982,000, compared with $1.5 million in revenues for the first quarter of 2004. Revenues in both periods were generated primarily from royalties on sales by Mylan Pharmaceuticals of Pfizer’s 30 mg generic Procardia XL®. A decrease in Mylan’s net sales of the product and the corresponding decrease in royalties due to the company primarily accounted for the decrease in revenues for the first quarter of 2005 compared with the first quarter of 2004.
Net loss for the first quarter of 2005 was $8.9 million, or $0.41 per share, compared with a net loss of $4.8 million, or $0.26 per share, in the first quarter of 2004.
Selling, general and administrative expenses for the first quarter of 2005 were $5.3 million, compared with $2.3 million in the first quarter of 2004. The increase in 2005 expenses is primarily attributable to a one-time charge of approximately $3.0 million in the first quarter of 2005 that was recorded by the Company in connection with the agreement it entered into with Tod Hamachek, the Company’s former Chairman and Chief Executive Officer, upon his resignation in February 2005. The $3.0 million charge includes a non-cash charge of approximately $2.4 million relating to the accelerated vesting and extension of exercise periods of stock options held by Mr. Hamachek. This compensation charge accounted for $0.14 per share of the net loss for the first quarter of 2005.
Research and product development expenses in the first quarter of 2005 were $5.1 million, compared with $4.1 million in the first quarter of 2004. The primary driver of the increase in the first quarter of 2005 was increased spending on products in the Company’s development pipeline that are in proof-of-principle biostudies.
Robert J. Hennessey, President and Chief Executive Officer of Penwest, said, “As we continue to execute our drug development strategy, we took steps in the first quarter to advance the CNS and other product opportunities in our portfolio and are pleased with the progress we are making. As we announced earlier this week, we have entered into a collaboration with Prism Pharmaceuticals to market PW2101 in the United States and Canada, and we continue to expect to receive an action letter from the FDA for this product by the end of June.”
At March 31, 2005, Penwest had $66.8 million in cash and investments, compared with cash and investments of $74.4 million as of December 31, 2004.

Penwest Pharmaceuticals
Penwest develops pharmaceutical products based on innovative oral drug delivery technologies. We are focusing our development efforts principally on products that address diseases of the central nervous system. The foundation of our technology platform is TIMERx®, an extended release delivery system that is adaptable to soluble and insoluble drugs and that is flexible for a variety of controlled release profiles. We have also developed two additional oral drug delivery systems, Geminex® and SyncroDose™. Geminex is a dual drug delivery system that is designed to provide independent release of different active ingredients contained in a drug, and SyncroDose is a drug delivery system that is designed to release the active ingredient of a drug at the desired site and time in the digestive tract.
