United Therapeutics Corporation (Nasdaq: UTHR), a public benefit corporation, today announced record financial results for the quarter ended September 30, 2025, driven by continued year-over-year revenue growth in key products such as Tyvaso^® and Orenitram^®. Total revenues in the third quarter of 2025 grew seven percent year-over-year to $799.5 million, compared to $748.9 million in the third quarter of 2024.

"Our commercial and clinical teams continue to deliver record results, validating our strategic objectives," said Martine Rothblatt, Chairperson and Chief Executive Officer of United Therapeutics. "The breakthrough results from our TETON-2 study in idiopathic pulmonary fibrosis could significantly broaden our therapeutic reach and accelerate our growth."

Michael Benkowitz, President and Chief Operating Officer of United Therapeutics, added, "This quarter we again achieved record total revenue and continued our double-digit growth for Tyvaso, reflecting a clear indication of the growing demand for our products. With laser focus and fierce determination, we are confident in our ability to sustain our growth trajectory."

Third Quarter 2025 Financial Results

Key financial highlights include (dollars in millions, except per share data):

Revenues

The table below presents the components of total revenues (dollars in millions):

Total Tyvaso revenues grew by 10 percent to $478.0 million in the third quarter of 2025, compared to $433.8 million in the third quarter of 2024.

The growth in Tyvaso DPI revenues resulted primarily from an increase in quantities sold of $58.1 million and, to a lesser extent, a price increase, partially offset by higher gross-to-net revenue deductions. The increase in Tyvaso DPI quantities sold was primarily due to continued growth in the number of patients following the product’s launch and, to a lesser extent, increased commercial utilization following the implementation of the Medicare Part D benefit redesign under the Inflation Reduction Act (IRA).

The decrease in Nebulized Tyvaso revenues resulted primarily from higher gross-to-net revenue deductions and a decrease in quantities sold.

The growth in Orenitram revenues resulted primarily from an increase in quantities sold of $11.7 million and, to a lesser extent, a price increase. The increase in quantities sold was driven, at least in part, by increased commercial utilization following the implementation of the Medicare Part D benefit redesign under the IRA.

The decrease in Unituxin revenues resulted primarily from a decrease in quantities sold, partially offset by a price increase.

The table below presents the breakdown of total revenues between the United States and rest-of-world (ROW) (in millions):

Expenses

Cost of sales. The table below summarizes cost of sales by major category (dollars in millions):

Cost of sales, excluding share-based compensation. Cost of sales for the three months ended September 30, 2025 increased as compared to the same period in 2024, primarily due to increases in: (1) royalty expense resulting from a growth in revenues; and (2) inventory reserve expense.

Research and development. The table below summarizes the nature of research and development expense by major expense category (dollars in millions):

Research and development, excluding share-based compensation. Research and development expense for the three months ended September 30, 2025 increased as compared to the same period in 2024, primarily due to: (1) increased expenditures related to manufactured organ and organ alternative projects; and (2) a $5.0 million milestone payment for drug delivery technologies.

Selling, general, and administrative. The table below summarizes selling, general, and administrative expense by major category (dollars in millions):

General and administrative, excluding litigation accrual and share-based compensation. General and administrative expense for the three months ended September 30, 2025 increased as compared to the same period in 2024, primarily due to increases in: (1) personnel expense due to growth in headcount; (2) legal expenses related to litigation matters; and (3) branded prescription drug fee expense associated with sales of Tyvaso DPI.

Litigation accrual. In the third quarter of 2024, we accrued a liability of $65.1 million related to ongoing litigation with Sandoz Inc. This liability was $73.3 million as of September 30, 2025. We currently do not expect that the amount of any loss in excess of this accrual would be material to our financial results; however, the amount ultimately payable, if any, could be higher or lower than this amount depending on the amount of post judgment interest and the outcome of appeals. The litigation accrual is included within selling, general, and administrative in our consolidated statements of operations.

Sales and marketing, excluding share-based compensation. Sales and marketing expense for the three months ended September 30, 2025 increased as compared to the same period in 2024, primarily due to increases in: (1) marketing expense; (2) personnel expense due to growth in headcount; and (3) sales commissions.

Share-based compensation. The table below summarizes share-based compensation expense by major category (dollars in millions):

Income tax expense. Income tax expense for the three months ended September 30, 2025 and 2024 was $99.3 million and $79.5 million, respectively. Our effective income tax rate (ETR) for the three months ended September 30, 2025 and 2024 was 23 percent and 20 percent, respectively. Our ETR for the three months ended September 30, 2025 increased compared to our ETR for the three months ended September 30, 2024, primarily due to year-over-year changes in actual and forecasted annual pre-tax earnings.

Share Repurchase. We entered into accelerated share repurchase agreements (ASR agreements) with Citibank, N.A. to repurchase approximately $1.0 billion of our common stock in each of August 2025 and March 2024 ($2.0 billion in the aggregate). During the three months ended September 30, 2025 and September 30, 2024, we received deliveries of 2,638,616 shares and 90,403 shares, respectively, under these ASR agreements.
