Lilly ICOS LLC Reports Results for 2004

January 26, 2005
BOTHELL, Wash. and INDIANAPOLIS, Ind., Jan 26, 2005 /PRNewswire via COMTEX/ -- "We are delighted that Cialis generated 2004 worldwide sales of $552 million," commented Paul N. Clark, ICOS Chairman and CEO. "Sales of Cialis in the U.S. were $207 million in 2004 and $53 million in the fourth quarter of 2004. During the 2004 fourth quarter, Cialis' monthly total U.S. prescriptions increased 18% sequentially from the third quarter of 2004 and, in December, Cialis achieved a new high of 20% market share for total prescriptions.(2) Overall, during 2004, Cialis steadily gained market share in major Lilly ICOS territories outside of the United States and, for November 2004, market share of Cialis ranged from 22% in Spain to 44% in France.(3)"

Clark continued, "While our U.S. prescription volume grew significantly during the 2004 fourth quarter, sequential quarterly sales, from Lilly ICOS into the wholesale channel, decreased due to our efforts to reduce channel inventory, beginning in December 2004. As a result, based on the information available today, we estimate there was approximately a $15 million reduction of wholesaler inventories during December 2004 and we anticipate there will be further reductions of wholesaler inventories in the first quarter of 2005. There also was some expected reduction in wholesaler inventories during October 2004, following the 6% price increase implemented on September 30, 2004. We continue to expect Lilly ICOS to achieve profitability around mid- 2005."

Khoso Baluch, Lilly Vice President, U.S. Diabetes and Family Health Business Unit stated, "Early in the fourth quarter in the U.S., we introduced a variety of new marketing initiatives. We believe we are already seeing the results of those new programs. Cialis' effective positioning and highly successful launch campaign earned it the 'Marketing Team of the Year' award from Medical Marketing and Media in the January 2005 issue."

Baluch added, "We begin 2005 with excitement. We will continue to invest to support our well-differentiated product and to further grow Cialis' market share."

2004 Fourth Quarter Financial Results

For the three months ended December 31, 2004, Lilly ICOS reported a net loss of $31.4 million, compared to a net loss of $57.7 million for the three months ended December 31, 2003.

Total Lilly ICOS revenue for the fourth quarter of 2004 was $125.5 million, compared to $69.2 million for the fourth quarter of 2003. Lilly ICOS revenue for the 2004 period includes $6.8 million in royalties on sales reported by Lilly, compared to $6.3 million in royalty revenue for the fourth quarter of 2003. The increase in Lilly ICOS revenue reflects the U.S. and Canadian launches of Cialis beginning in November 2003, as well as the global expansion of Cialis to approximately 100 countries today.

In December 2004, Lilly ICOS took action to reduce channel inventory to targeted levels. As a result, based on information currently available, the company estimates that approximately $15 million of wholesaler inventory reductions occurred during that month and the company anticipates there will be further reductions of wholesaler inventories in the first quarter of 2005.

Cost of sales, including royalties payable by Lilly ICOS equal to 5% of its net product sales, was 8.7% in the fourth quarter of 2004, compared to 9.5% in the fourth quarter of 2003.

Selling, general and administrative expenses increased $27.4 million from the fourth quarter of 2003, to $130.4 million in the fourth quarter of 2004. This is primarily due to increased 2004 sales and marketing costs as Cialis was launched in the United States and Canada in November 2003.

Research and development expenses were $16.2 million in the fourth quarter of 2004, compared to $17.9 million in the fourth quarter of 2003.

2004 Full-Year Financial Results

For the year ended December 31, 2004, Lilly ICOS reported a net loss of $262.0 million, compared to a net loss of $174.7 million for the year ended December 31, 2003. As expected, the increased loss in 2004 was a result of the costs associated with launching Cialis in North America.
