**Fourth Quarter 2025 Compared to Fourth Quarter 2024.** 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.

(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 regulatory 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 regulatory approval, and internal facilities-related expenses, including depreciation, related to research and development activities.

(3)See *Share-based compensation* section below for discussion.

(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 assets. During the year ended December 31, 2025, we recorded (a) $42.2 million in expense related to milestone payments for drug delivery device and formulation technologies; and (b) $10.8 million in expense related to adjustments to the fair value of contingent consideration obligations for manufactured organ and organ alternative projects. 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.

*Research and development, excluding share-based compensation*. The increase in research and development expense for the year ended December 31, 2025, as compared to the same period in 2024, was primarily due to: (1) increased expenditures related to manufactured organ and organ alternative projects; and (2) increased expenditures for drug delivery device and formulation technologies.

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

(2)See *Share-based compensation* section below for discussion.

(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.

---

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.
