Conference Call Scheduled for Wednesday, November 3, 2004 at 9:00 a.m. E.T.

Silver Spring, MD, November 3, 2004: United Therapeutics Corporation (NASDAQ: UTHR) today announced financial results for the third quarter ended September 30, 2004.

“We are very pleased to report that United Therapeutics has performed well financially, which helps to enable our continued spending on developing new medicines,” said Martine Rothblatt, Ph.D., United Therapeutics’ Chairman and Chief Executive Officer. “United Therapeutics’ consolidated revenues for the quarter ended September 30, 2004 totaled $20.0 million, representing a 33% increase over the same quarter in 2003,” observed Dr. Rothblatt. “Our net income for the quarter was $6.3 million or $0.29 per basic share.”

Financial Results

Revenues grew to $20.0 million in the third quarter of 2004, as compared to $15.0 million in the third quarter of 2003. United Therapeutics earned quarterly net income of $6.3 million or $0.29 per basic share in the third quarter of 2004, as compared to a net loss of $1.3 million or $0.06 per basic share in the third quarter of 2003.

Research and development expenses were $7.3 million in the third quarter of 2004, as compared to $9.4 million in the third quarter of 2003. The decrease of approximately $2.1 million was due primarily to reduced expenses of approximately $1.3 million for the cancer program and approximately $470,000 for the Remodulin related programs. Selling, general and administrative expenses were approximately $4.8 million in the third quarter of 2004, as compared to approximately $5.6 million in the third quarter of 2003. The decrease of approximately $800,000 was due primarily to decreased sales and marketing expenses related mostly to arginine products.

Interest income was $771,000 in the third quarter of 2004, as compared to interest income of $637,000 in the third quarter of 2003.
