PRESS RELEASE

SILVER SPRING, Md. & RESEARCH TRIANGLE PARK, N.C.--(BUSINESS WIRE)-- United Therapeutics Corporation (Nasdaq: UTHR), a public benefit corporation, today announced its financial results for the quarter ended March 31, 2026. Total revenues in the first quarter of 2026 decreased by two percent year-over-year to $781.5 million, compared to $794.4 million in the first quarter of 2025.

“In the first quarter of 2026, we extended our run of clinical success, with positive results from both our ADVANCE OUTCOMES and TETON-1 studies,” said Martine Rothblatt, Ph.D., Chairperson and Chief Executive Officer of United Therapeutics. “These readouts have the potential to meaningfully expand the breadth of our future growth and support further revenue diversification while reinforcing our long-term commitment to advancing therapies for patients with serious cardiopulmonary and respiratory disease. Moreover, given these successes, we’re excited to announce our development plans in pulmonary hypertension and fibrosis for ralinepag DPI, which we believe has the potential to achieve once-daily dosing and help broaden our therapeutic reach greater than ever before.”

Michael Benkowitz, President and Chief Operating Officer of United Therapeutics, added, “While the competitive landscape for inhaled prostacyclins remains dynamic, our continued growth for Tyvaso DPI reflects the resilience of our commercial strategy. Going forward, we are committed to further sharpening our execution with relentless drive and unwavering discipline to return to sequential quarterly revenue growth across our commercial portfolio in the near term.”

First Quarter 2026 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 decreased by two percent to $457.5 million in the first quarter of 2026, compared to $466.3 million in the first quarter of 2025, driven by a decrease in Nebulized Tyvaso revenues, partially offset by growth in Tyvaso DPI revenues. The growth in Tyvaso DPI revenues resulted primarily from an increase in quantities sold of $16.0 million and, to a lesser extent, a price increase. The decrease in Nebulized Tyvaso revenues resulted primarily from a decrease in U.S. quantities sold of $33.3 million and, to a lesser extent, a decrease in international revenues, partially offset by a price increase. The decrease in Remodulin revenues resulted primarily from a decrease in quantities sold of $11.1 million. The growth in Orenitram revenues resulted primarily from an increase in quantities sold of $10.2 million.

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. The increase in cost of sales for the three months ended March 31, 2026, compared to the same period in 2025, was mainly due to an increase in inventory reserve expense. Of this increase amount, $26.8 million relates to an estimated loss from a commercial supply agreement that we maintain to provide sufficient Tyvaso DPI inventory to meet the needs of our patients.

Research and development expense. 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. The decrease in research and development expense for the three months ended March 31, 2026, as compared to the same period in 2025, was primarily due to a decrease in milestone payments for drug delivery device technologies, partially offset by an increase in personnel expenses.

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

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

The increase in share-based compensation expense for the three months ended March 31, 2026, as compared to the same period in 2025, was primarily due to an increase in the number of unvested and outstanding performance-based stock options during the three months ended March 31, 2026, as compared to the same period in 2025.

Other expense, net. The change in other expense, net for the three months ended March 31, 2026, as compared to the same period in 2025, was primarily due to net unrealized losses on equity securities.

Income tax expense. Income tax expense for the three months ended March 31, 2026 and 2025 was $43.4 million and $101.3 million, respectively. Our effective income tax rate (ETR) for the three months ended March 31, 2026 and 2025 was 14 percent and 24 percent, respectively. Our ETR for the three months ended March 31, 2026 decreased compared to our ETR for the three months ended March 31, 2025, primarily due to increased excess tax benefits from share-based compensation.

Share repurchase. In March 2026, our Board of Directors approved a share repurchase program authorizing up to $2.0 billion in aggregate repurchases of our common stock, which program expires on March 9, 2027. In March 2026, we also entered into accelerated share repurchase agreements (the 2026 ASR agreements) with Citibank, N.A. to repurchase approximately $1.5 billion of our common stock. During the three months ended March 31, 2026, we received 2,164,459 shares of our common stock under the 2026 ASR agreements. As of March 31, 2026, $500 million remained available under our Board's share repurchase authorization through March 9, 2027.
