REPORTS FINANCIAL RESULTS FOR THE THIRD QUARTER 2002 DURHAM, N.C., NOVEMBER 6, 2002 -- Triangle Pharmaceuticals, Inc. (Nasdaq: VIRS) today reported financial results for the third quarter ended September 30, 2002. For the quarter ended September 30, 2002, the Company reported a net loss of $1,055,000, or ($0.01) per share, compared to a net loss of $18,197,000, or ($0.35) per share in the third quarter of 2001. For the nine months ended September 30, 2002, the Company reported a net loss of $17,775,000, or ($0.23) per share, compared to a net loss of $62,218,000, or ($1.32) per share for the same nine-month period in 2001. The third quarter results were impacted by a one-time event as described below. Cash, cash equivalents and total investments were $68,270,000 on September 30, 2002, compared to $108,155,000 on December 31, 2001. Revenues for the third quarter of 2002 were $14,556,000, reflecting recognition of substantially all remaining deferred revenue under the Company's strategic alliance with Abbott Laboratories which was terminated in July 2002, compared to $1,271,000 of revenue for the third quarter of 2001. Termination of the alliance resulted in the one-time, non-cash recognition of approximately $14,200,000 of collaborative revenue. Total operating expenses were $16,078,000 for the third quarter of 2002 as compared to $20,241,000 for the third quarter of 2001. For the nine months ended September 30, 2002, the Company reported revenues of $16,625,000, operating expenses of $46,081,000, and a net loss of $17,775,000 compared to revenues of $4,760,000, operating expenses of $69,791,000, and a net loss of $62,218,000 for the nine months ended September 30, 2001. Daniel Welch, Chairman and Chief Executive Officer of Triangle stated, "Triangle's strong progress toward commercialization continues with the acceptance by the Food and Drug Administration (FDA) of our New Drug Application (NDA) for Coviracil on November 1, 2002. The next steps in this progression are to complete two important tasks by year end. First, to submit a Marketing Authorisation Application (MAA) to commercialize Coviracil in the European Union and second, to complete our evaluation of alternative strategies for the commercialization of Coviracil." Robert Amundsen, Executive Vice President and Chief Financial Officer, commented on the results, "Our operating losses for the third quarter and for the nine months ending September 30, 2002 were significantly lower than in the corresponding 2001 periods due to substantially increased revenue associated with our termination of the Abbott Alliance and significantly curtailing our operating expenses. With our recent news regarding the FDA's acceptance of our Coviracil NDA, we expect our operating expenses to increase in 2003. We will be in a position to give guidance on our projected 2003 results in the first quarter of 2003 when we announce our Coviracil commercialization plans."
