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

Total Tyvaso revenues grew by 12 percent to $464.3 million in the fourth quarter of 2025, compared to $415.9 million in the fourth quarter of 2024. The growth in Tyvaso DPI revenues resulted primarily from an increase in quantities sold of $63.5 million, primarily due to continued growth in the number of patients following the product's launch and, to a lesser extent, increased commercial utilization following implementation of the Medicare Part D benefit redesign under the Inflation Reduction Act (IRA). The decrease in Nebulized Tyvaso revenues resulted primarily from a decrease in quantities sold. The growth in Orenitram revenues resulted primarily from an increase in quantities sold of $10.3 million, driven, at least in part, by increased commercial utilization following the implementation of the Medicare Part D benefit redesign under the IRA.

Full Year 2025 Compared to Full Year 2024. Total Tyvaso revenues grew by 16 percent to $1,878.2 million in 2025, compared to $1,620.4 million in 2024, driven by growth in Tyvaso DPI revenues. The growth in Tyvaso DPI revenues resulted from an increase in quantities sold of $268.5 million, primarily due to continued growth in the number of patients following the product's launch and, to a lesser extent, increased commercial utilization following implementation of the Medicare Part D benefit redesign under the IRA. The growth in Orenitram revenues resulted primarily from an increase in quantities sold of $46.0 million, driven, at least in part, by increased commercial utilization following the implementation of the Medicare Part D benefit redesign under the IRA.

Cost of sales, excluding share-based compensation. The increase in cost of sales for the quarter and year ended December 31, 2025, as compared to the same periods in 2024, was primarily due to increases in (1) royalty expense resulting from a growth in revenues (2) inventory reserve expense and (3) the cost of products and services sold.

Research and development, excluding share-based compensation.

(1)Excluding impairment of PP E and litigation accrual. See Impairment of PP E and Litigation accrual sections below.

(3)Calculation is not meaningful.

General and administrative, excluding impairment of PP E, litigation accrual, and share-based compensation. The increase in general and administrative expense for the quarter ended December 31, 2025, as compared to the same period in 2024, was primarily due to increases in (1) personnel expense due to growth in headcount and (2) consulting expenses. The increase in general and administrative expense for the year ended December 31, 2025, as compared to the same period in 2024, was primarily due to increases in (1) personnel expense due to growth in headcount and (2) legal expenses related to litigation matters.

Impairment of PP E. During the second quarter of 2025, we recorded a $21.7 million impairment charge to write down the carrying value of certain PP E.

Litigation accrual. During the years ended December 31, 2025 and 2024, we recorded accruals of $3.0 million and $71.1 million, respectively, related to ongoing litigation with Sandoz Inc. 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, 2025. 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, 2025, as compared to the same period in 2024, was primarily due to increases in (1) personnel expense due to growth in headcount and (2) marketing 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 and year ended December 31, 2025, as compared to the same periods in 2024, was primarily due to (1) an increase in restricted stock unit expense due to a greater number of outstanding performance-based restricted stock units during the quarter and year ended December 31, 2025, as compared to the same periods in 2024 and (2) an increase in stock option expense due to a greater number of unvested and outstanding performance-based stock options during the quarter and year ended December 31, 2025, as compared to the same periods in 2024, partially offset by a decrease in STAP expense, as all remaining STAP awards were exercised during the first quarter of 2025.

Other income (expense), net. The changes in other income (expense), net for the quarter and year ended December 31, 2025, as compared to the same periods in 2024, were primarily due to net unrealized gains on equity securities.

Income tax expense. Income tax expense was $379.2 million for the year ended December 31, 2025, as compared to $343.9 million for the same period in 2024. Our effective income tax rate was approximately 22 percent for the years ended December 31, 2025 and 2024.

Share repurchases. 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 August 2025 and March 2024 ($2.0 billion in the aggregate). During the quarter and year ended December 31, 2025, we received 3,882 shares and 2,642,498 shares of our common stock, respectively, under these ASR agreements. During the quarter and year ended December 31, 2024, we received zero and 3,547,374 shares of our common stock, respectively, under these ASR agreements.
