Previous wording

Sales of our treprostinil-based therapies — Tyvaso DPI, Nebulized Tyvaso, Remodulin, and Orenitram — comprise the vast majority of our revenues. Substantially decreased sales of any of these products could have a material adverse impact on our operations. A wide variety of events, such as withdrawal of regulatory approvals or substantial changes in prescribing practices or dosing patterns, many of which are described in other risk factors below, could cause sales of these products to materially decline, or to grow more slowly than expected. Our net revenues could also be negatively impacted by pricing pressure as a result of competitive challenges, the IRA, and other drug price reduction initiatives. The availability of generic versions of our products has negatively impacted our revenues, and these and additional generic products launched in the future may continue to do so. The approval and launch of new therapies may negatively impact sales of our current and potential new products. Sales may decrease if any third party that manufactures, markets, distributes, or sells our commercial products cannot do so satisfactorily, or we cannot manage our internal manufacturing processes. Finally, if demand for our Tyvaso products does not meet our expectations, the revenue opportunity for our treprostinil products could be significantly lower than we expect.

Previous wording

To obtain approvals from the FDA and international regulatory agencies to sell new products, to expand the product labeling for our existing products, or launch new delivery devices for our existing products, we must conduct clinical trials demonstrating that our products are safe and effective. Regulators have substantial discretion over the approval process. Regulators may require us to amend ongoing trials or perform additional trials, which have in the past and could in the future result in significant delays and additional costs and may be unsuccessful. Delays and costs associated with regulatory requirements to change or add trials have sometimes caused us to discontinue efforts to develop a particular product, and may do so again in the future. If our clinical trials are not successful, or we fail to address identified deficiencies adequately, we will not obtain required approvals to market the new product or new indication. We cannot predict with certainty how long it will take, or how much it will cost, to complete necessary clinical trials or obtain regulatory approvals of our current or future products. The time and cost needed to complete clinical trials and obtain regulatory approvals varies by product, indication, and country. In addition, failure to obtain, or delays in obtaining, regulatory approval has in the past and could in the future require us to recognize impairment charges.

Numerous treatments compete with our commercial therapies. For example, for the treatment of PAH, we compete with over fifteen branded and generic drugs. Sales of a generic version of Adcirca launched in August 2018 have had a material adverse impact on our sales of Adcirca. The availability of generic treprostinil injection in the United States could materially impact our revenues, and generic competition materially impacted our Remodulin revenues outside the United States. Our competitors are also developing numerous new products that may compete with ours, including products intended to treat PAH and/or PH-ILD. For example, Merck received approval for Winrevair (sotatercept-csrk) in March 2024, which competes with our treprostinil-based products. In addition, in May 2025 Liquidia received FDA approval of Yutrepia for PAH and PH-ILD, which now competes with our treprostinil-based products. Additional treatments, such as Insmed Corp.’s TPIP, are in late-stage clinical trials for treatment of PAH and/or PH-ILD. Each of these products could potentially materially adversely affect our revenues. There are also two therapies approved for the treatment of IPF, and we are aware of a significant number of additional therapies being developed for the treatment of IPF, which would compete with Tyvaso DPI and Nebulized Tyvaso if either of them is ultimately approved for that indication.

•Unituxin is a chimeric monoclonal antibody that has stringent quality control and stability requirements. The drug substance manufacturing process involves a complex, multi-step cell culture and purification process. Many biologic products, including Unituxin, are particularly sensitive to the conditions under which they are manufactured. Supplier-driven changes to any of the raw materials or components used in the manufacture of Unituxin, such as discontinuation or alteration, could have unintended impacts on the quality and shelf life of Unituxin and may inhibit or prevent our ability to supply acceptable finished product in sufficient quantities or at all. Batches of Unituxin that fail to meet certain specifications cannot be sold into the market. We have a limited capacity to produce batches of Unituxin. If a sufficient number of batches fail, we could face a shortage of drug product. Furthermore, Unituxin has a limited shelf life, which impacts our ability to stockpile inventory at comparable levels to our other commercial products.

We are encountering limitations on our ability to supply Unituxin to our distributor in Japan, which caused our distributor to delay starting new patients on this therapy in Japan. We are proactively engaging with the FDA to adjust certain manufacturing specifications for Unituxin to reduce the risk of a shortage in the United States. These efforts may prove unsuccessful. Furthermore, Unituxin has a limited shelf life, which impacts our ability to stockpile inventory at comparable levels to our other commercial products.

Payers and pharmacy benefit managers have developed mechanisms to limit the benefits patients receive under co-pay assistance programs through imposing so-called co-pay accumulator or maximizer programs. These programs do not allow a patient using co-pay assistance to count the manufacturer’s co-payment contribution toward their annual out-of-pocket payment maximum/deductible. Once the co-pay benefit has been exhausted, patients are faced with paying the full out-of-pocket maximum/deductible. Some states have passed legislation to limit the use of co-pay accumulator programs, while some other states have indicated that these programs should be allowed to limit cost of care and encourage patients to use lower cost generics.

During the fourth quarter of 2023, we acquired IVIVA and Miromatrix. We may continue to seek to expand in part through acquisitions of complementary businesses, products, and technologies. The success of this strategy will depend on our ability to identify, and the availability of, suitable acquisition candidates. We may incur costs related to an acquisition but may be unable or unwilling to consummate the proposed transaction. Acquisitions involve numerous risks, including: the ability to realize anticipated synergies and manage the integration of personnel, products, and acquired infrastructure and controls; potential increases in operating costs; managing geographically remote operations; the diversion of management's attention from other business concerns; potential disruptions in ongoing operations during integration; risks inherent in entering markets and sectors in which we have limited or no direct experience; and the potential loss of key employees, customers, or vendors and other business partners of the acquired companies. External factors, such as compliance with law, may also impact the successful integration of an acquired business. Acquisitions could involve dilutive issuances of equity securities, the incurrence of debt, one-time write-offs of goodwill (or IPR&D assets), and substantial amortization expenses of other intangible assets. We may be unable to obtain financing on favorable terms, or at all, if necessary to finance future acquisitions, which may make acquisitions impossible or more costly. The terms of financing we obtain may be onerous and restrict our operations. Further, certain acquisitions may be subject to regulatory approval, which can be time consuming and costly to obtain or may be denied, and if obtained, the terms of such regulatory approvals may limit our ongoing operations or require us to divest assets.
