July 26, 2000
BIOCRYST REPORTS SECOND QUARTER 2000 FINANCIAL RESULTS Birmingham, Alabama -- July 26, 2000 -- BioCryst Pharmaceuticals, Inc. (Nasdaq NM: BCRX) today announced financial results for the second quarter ended June 30, 2000. The Company reported revenues for the second quarter of $1,585,000, compared to $2,502,000 in the second quarter of 1999. The net loss for the quarter ended June 30, 2000 was $1,995,000, or $0.11 per share, compared to a net loss of $251,000, or $0.02 per share, for the same period last year.

Revenues decreased in the second quarter of 2000 versus the comparable period in 1999, primarily due to the fact that there were no milestone payments received during the second quarter of 2000. The increase in total expenses in the second quarter of 2000 compared to the second quarter of 1999 was generally due to increases in contracted research costs at various institutions, and supplies and personnel costs, which were partially offset by a decrease in clinical trial expenses.

Revenues for the six months ended June 30, 2000 were $6,808,000, compared to $3,041,000 in the six months ended June 30, 1999. The net loss for the six months ended June 30, 2000 was $137,000, or $0.01 per share, compared to a net loss of $2,651,000, or $0.18 per share, for the same period last year. As of June 30, 2000, the Company had cash, cash equivalents and investments of $71,294,000

The increase in revenues in the first six months of 2000 was primarily attributable to a $4.0 million milestone payment received from The R.W. Johnson Pharmaceutical Research Institute (RWJPRI). in February 2000 versus a $2.0 million milestone payment received in June 1999. In addition, interest income increased $1.5 million primarily due to the investment of funds received from the November 1999 public offering. The increase in total expenses in the first six months of 2000 compared to the same period in 1999 was generally due to increases in contracted research costs at various institutions, supplies, personnel costs, royalty expense and fees related to a new Alabama share tax assessment, which were partially offset by a decrease in clinical trial expenses and a reduction in legal expenses.

During the quarter, BioCryst further strengthened its drug research and development efforts and drug candidate pipeline. BioCryst and Emory University signed an agreement to facilitate the discovery of new drug candidates designed to inhibit hepatitis C polymerase. In addition, BioCryst in-licensed a series of potent inhibitors of purine nucleoside phosphorylase from Albert Einstein College of Medicine of Yeshiva University and Industrial Research, Ltd. BioCryst has initiated preclinical studies with the lead compound in the series, BCX-1777, for treatment of psoriasis.
