United Therapeutics Corporation Reports Second Quarter 2007 Financial Results

SILVER SPRING, Md., July 31 /PRNewswire-FirstCall/ -- United Therapeutics Corporation today announced financial results for the quarter ended June 30, 2007.

“We are pleased to report that United Therapeutics has surpassed $50 million in quarterly revenues for the second quarter. Net income for the quarter was $5.8 million, or $0.28 per basic share,” said Martine Rothblatt, Ph.D., United Therapeutics’ Chairman and Chief Executive Officer.

Financial Results

Revenues grew to $51.8 million in the second quarter of 2007, as compared to $40.2 million in the second quarter of 2006. Gross margins from sales were $45.8 million in the second quarter of 2007, as compared to $36.0 million in the second quarter of 2006. The increases in revenues and gross margins resulted primarily from growth in sales of Remodulin. Net income was $5.8 million or $0.28 per basic share in the second quarter of 2007, as compared to net income of $7.7 million or $0.33 per basic share in the second quarter of 2006.

Research and development expenses consist primarily of salaries and related expenses, costs to acquire pharmaceutical products and product rights for development, and amounts paid to contract research organizations, hospitals and laboratories for the provision of services and materials for drug development and clinical trials. The table below summarizes research and development by major project and non-project components (dollars in thousands): Three Months Ended June 30, Percentage 2007 2006 Change Project and non-project: Cardiovascular $9,269 $6,596 40.5 % Cancer 4,061 2,462 65.0 % Infectious disease 200 180 11.1 % Stock option 2,981 2,173 37.2 % Other 1,459 1,203 21.3 % Total research and development expense $17,970 $12,614 42.5 %

The increase in expenses for our cardiovascular program was primarily attributable to our oral and inhaled projects, each of which required approximately $1.5 million more expenses over the same period in 2006. The increase in expenses for the cancer program was primarily related to the development of the manufacturing process for OvaRex(R) in our Silver Spring, Maryland, facility.

Selling, general and administrative expenses consist primarily of salaries, travel, office expenses, insurance, professional fees, provision for doubtful accounts receivable, depreciation and amortization. The table below summarizes selling, general and administrative expenses by major categories (dollars in thousands):

Three Months Ended June 30, Percentage 2007 2006 Change Category: General and administrative $9,066 $6,465 40.2 % Sales and marketing 5,708 3,361 69.8 % Stock option 5,700 2,045 178.7 % Total selling, general and administrative expense $20,474 $11,871 72.5 %

The increase in general and administrative expenses was due primarily to increased expenses of approximately $1.1 million of salaries and related expenses from headcount growth to support our expanding operations. The increase in sales and marketing related expenses was primarily due to an increase in salaries and related expenses of approximately $1.8 million due to an increase in headcount to support our Remodulin sales growth. The increase in stock option expense of approximately $3.7 million represents increased non-cash employee stock option expense and accruals.

An income tax expense of approximately $3.1 million was recognized for the three months ended June 30, 2007, as compared to approximately $6.2 million for the three months ended June 30, 2006. The income tax provision was based on the estimated annual effective tax rate for the entire year. The estimated effective tax rate is subject to adjustment in subsequent quarterly periods as the estimates of pre-tax income for the year are adjusted. The effective tax rate for the six months ended June 30, 2007 and 2006, was approximately 35 percent and 44 percent, respectively. However, we do not anticipate paying significant federal income taxes for 2007 due to the availability of $38.5 million of net operating loss carryforwards and $50.3 million of research tax credits.

During the six months ended June 30, 2006, we recognized a non-cash and non-recurring charge of $2.0 million for the impairment of the HeartBar(R) tradename. During the six months ended June 30, 2007, we issued 200,000 shares of our common stock to Toray in connection with an amended license agreement for modified release beraprost. The issuance of shares resulted in an $11.0 million non-recurring expense because the licensed product has not yet obtained regulatory approval for commercial sales. If these non-cash, non- recurring items were not recognized during the six-month periods ending June 30, 2007 and 2006, respectively, pro forma net income would have been as follows (in thousands, except per share data):

Six Months Ended June 30, 2007 2006 Net income, as reported $3,025 $9,980 Add back: Impairment of HeartBar tradename - 2,024 License fee from issuance of stock 11,013 - Less tax effect of non-recurring item (3,905) (898) Pro forma net income $10,133 $11,106 Earnings per share, as reported: Basic $0.14 $0.42 Diluted $0.14 $0.39 Pro forma earnings per share(1): Basic $0.48 $0.47 Diluted $0.46 $0.43 (1) Calculated by dividing pro forma net income from above by weighted average shares outstanding, as reported below.
