United Therapeutics Corporation Reports Fourth Quarter and Full Year 2024 Financial Results

SILVER SPRING, Md. and RESEARCH TRIANGLE PARK, N.C., February 26, 2025 United Therapeutics Corporation (Nasdaq UTHR), a public benefit corporation, today announced its financial results for the quarter and year ended December 31, 2024. Full year 2024 revenues rose to a record $2.88 billion, reflecting 24% growth over 2023.

"I want to congratulate every Unitherian for their relentless dedication, which has allowed us to deliver a third consecutive year of record revenue," said Martine Rothblatt, Ph.D., Chairperson and Chief Executive Officer of United Therapeutics. "On top of that, our three-year cascade of clinical and regulatory events is under way both TETON studies in idiopathic pulmonary fibrosis are enrolled, facilitating data starting the second half of this year ralinepag, our potentially best-in-class once-daily oral prostacyclin agonist, will generate data next year and this month we announced FDA clearance to start the first potentially registration-enabling xenotransplantation study with our UKidney."

Michael Benkowitz, President and Chief Operating Officer of United Therapeutics, added, "Our commercial foundation continues to operate from a place of strength, propelled by robust fourth quarter performance across our product portfolio, which capped a record-setting year. We look forward to continuing this momentum in 2025 as our sales and marketing teams continue their efforts to ensure that prescribers are educated on the benefits of our broad array of treprostinil products, which are widely regarded as a cornerstone for treating pulmonary hypertension."

Fourth Quarter and Full Year 2024 Financial Results

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

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

(1)Net product sales include both the drug product and the respective inhalation device.

(2)Net product sales include sales of infusion devices, including the Remunity Pump.

Fourth Quarter 2024 Compared to Fourth Quarter 2023. Total Tyvaso revenues grew by 19 percent to $415.9 million in the fourth quarter of 2024, compared to $350.6 million in the fourth quarter of 2023. This growth was primarily driven by growth in Tyvaso DPI revenues, which resulted from an increase in quantities sold of $62.7 million and, to a lesser extent, a price increase, partially offset by higher gross-to-net deductions. The increase in Tyvaso DPI quantities sold was due to continued growth in the number of patients following the product's launch, including growth in utilization by patients with pulmonary hypertension associated with interstitial lung disease (PH-ILD) and, to a lesser extent, increased commercial utilization following implementation of the Part D redesign under the Inflation Reduction Act (IRA). The growth in Remodulin revenues resulted from an increase in U.S. Remodulin revenues and, to a lesser extent, an increase in international Remodulin revenues, driven, in both cases, by an increase in quantities sold. The increase in Orenitram revenues resulted from an increase in quantities sold and, to a lesser extent, a price increase. The increase in Orenitram quantities sold was driven, at least in part, by increased commercial utilization following the implementation of the Part D redesign under the IRA. The increase in Unituxin revenues resulted from an increase in quantities sold and a price increase.

Full Year 2024 Compared to Full Year 2023. Total Tyvaso revenues grew by 31 percent to $1,620.4 million in 2024, compared to $1,233.7 million in 2023. The growth in Tyvaso DPI revenues resulted from an increase in quantities sold of $269.2 million and, to a lesser extent, price increases, 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 (including by PH-ILD patients) and, to a lesser extent, increased commercial utilization following implementation of the Part D redesign under the IRA. The growth in nebulized Tyvaso revenues resulted primarily from an increase in quantities sold of $51.9 million and, to a lesser extent, a price increase. Growth in nebulized Tyvaso was also driven by continued growth in use by PH-ILD patients. The growth in Remodulin revenues resulted from an increase in U.S. Remodulin revenues, driven by an increase in quantities sold. The growth in Orenitram revenues resulted from an increase in quantities sold and, to a lesser extent, a price increase. The increase in Orenitram quantities sold was driven, at least in part, by increased commercial utilization following the implementation of the Part D redesign under the IRA. The growth in Unituxin revenues resulted from a price increase and an increase in quantities sold.

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

(1) Net product sales include both the drug product and the respective inhalation device.

(2) Net product sales include sales of infusion devices, including the Remunity Pump.

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

(1)See Share-based compensation below.

Cost of sales, excluding share-based compensation. The increase in cost of sales for the year ended December 31, 2024, as compared to the same period in 2023, was primarily due to an increase in Tyvaso DPI royalty expense and product costs driven by growth in Tyvaso DPI revenues.

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

(1)External research and development primarily includes fees paid to third parties (such as clinical trial sites, contract research organizations, and contract laboratories) for preclinical and clinical studies and payments to third-party contract manufacturers before FDA approval of the relevant product.

(2)Internal research and development primarily includes salary-related expenses for research and development functions, internal costs to manufacture product candidates before FDA approval, and internal facilities-related expenses, including depreciation, related to research and development activities.

(3)See Share-based compensation below.

(4)Other primarily includes upfront fees and milestone payments to third parties under license agreements related to development-stage products, adjustments to the fair value of our contingent consideration obligations, and costs to acquire certain in-process research and development (IPR D) assets. During the year ended December 31, 2024, we recorded $40.2 million and $8.0 million in expense related to upfront non-refundable licensing payments for drug delivery device technologies and ex vivo lung perfusion technology, respectively. During the quarter and year ended December 31, 2023, we recorded $46.0 million in IPR D expense in connection with the acquisition of IVIVA Medical, Inc. (IVIVA).

Research and development, excluding share-based compensation. The decrease in research and development expense for the quarter ended December 31, 2024, as compared to the same period in 2023, was primarily due to IPR D expense we recorded in connection with the acquisition of IVIVA during the quarter ended December 31, 2023 partially offset by increased expenditures related to manufactured organ and organ alternative projects and upfront non-refundable licensing payments related to ex vivo lung perfusion technology.

The increase in research and development expense for the year ended December 31, 2024, as compared to the same period in 2023, was due to (1) increased expenditures related to manufactured organ and organ alternative projects (2) non-refundable licensing payments for drug delivery device technologies and ex vivo lung perfusion technology and (3) increased expenditures related to the TETON studies of nebulized Tyvaso in patients with idiopathic pulmonary fibrosis and progressive pulmonary fibrosis. These increases were partially offset by the impact of an IPR D expense recorded during the year ended December 31, 2023 in connection with the acquisition of IVIVA, which expense did not recur in 2024.

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

(1)Excluding litigation accrual. See Litigation accrual section below.

(2)See Share-based compensation below.

(3)Calculation is not meaningful.

General and administrative, excluding litigation accrual and share-based compensation. The increase in general and administrative expense for the quarter and year ended December 31, 2024, as compared to the same periods in 2023, was primarily due to increases in (1) personnel expense due to growth in headcount (2) legal expenses related to litigation matters and (3) consulting expenses.

Litigation accrual. As of December 31, 2024, we accrued a liability of $71.1 million related to ongoing litigation with Sandoz Inc., reflecting the final judgment and post-judgment interest accrued through the end of 2024. 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, as discussed in Note 14-Litigation, to our consolidated financial statements included within our Annual Report on Form 10-K for the year ended December 31, 2024. The litigation accrual is included within selling, general, and administrative in our consolidated statements of operations.

Sales and marketing, excluding share-based compensation. The increase in sales and marketing expense for the year ended December 31, 2024, as compared to the same period in 2023, was primarily due to increases in (1) personnel expense due to growth in headcount (2) marketing expenses and (3) consulting expenses.

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

The increase in share-based compensation expense for the quarter ended December 31, 2024, as compared to the same period in 2023, was primarily due to (1) an increase in stock option expense due to a greater number of awards granted in 2024, as compared to the same period in 2023 (2) an increase in restricted stock unit expense due to a greater number of awards remaining outstanding in 2024, as compared to the same period in 2023 and (3) an increase in STAP expense driven by a two percent decrease in our stock price during the quarter ended December 31, 2024, as compared to a three percent decrease in our stock price for the same period in 2023. The increase in share-based compensation expense for the year ended December 31, 2024, as compared to the same period in 2023, was primarily due to (1) an increase in STAP expense driven by a 60 percent increase in our stock price during 2024, as compared to a 21 percent decrease in our stock price during 2023 (2) an increase in restricted stock unit expense due to a greater number of awards granted and remaining outstanding in 2024, as compared to the same period in 2023 and (3) an increase in stock option expense due to a greater number of awards granted in 2024, as compared to the same period in 2023.

Other (expense) income, net. The change in other (expense) income, net for the year ended December 31, 2024, as compared to the same period in 2023, was primarily due to net unrealized gains on equity securities.

Income tax expense. Income tax expense was $343.9 million for the year ended December 31, 2024, compared to $289.5 million for the same period in 2023. For the years ended December 31, 2024 and 2023, our effective income tax rates (ETR) were approximately 22 percent and 23 percent, respectively. Our ETR for the year ended December 31, 2024 decreased, compared to our ETR for the year ended December 31, 2023, primarily due to a decrease in nondeductible acquisition costs and an increase in excess tax benefits from share-based compensation, partially offset by an increase in nondeductible compensation.

Share repurchase. In March 2024, we entered into an accelerated share repurchase agreement (the ASR agreement) with Citibank, N.A. (Citi). Under the ASR agreement, we made an aggregate upfront payment of $1.0 billion to Citi and received an aggregate initial delivery of 3,275,199 shares of our common stock on March 27, 2024, which represented approximately 80 percent of the total shares that would be repurchased under the ASR agreement, measured based on the closing price of our common stock on March 25, 2024.

The share repurchase under the ASR agreement was divided into two tranches, resulting in upfront payments of $300 million and $700 million, respectively. The final settlement of the $300 million tranche occurred in June 2024, and we received an additional 181,772 shares of our common stock upon settlement. The final settlement of the $700 million tranche occurred in September 2024, and we received an additional 90,403 shares of our common stock upon settlement. In total, we repurchased 3,547,374 shares of our common stock under the ASR agreement that we currently hold as treasury stock in our consolidated balance sheets.
