Previous wording

We expect to incur significant expenses and operating losses for the foreseeable future as we advance our product candidates through clinical trials, seek regulatory approval and pursue commercialization of any approved product candidates. The future viability of our company will depend on our ability to fund future operations and capital requirements with additional capital from external financing.

Current wording

We expect to incur significant expenses and may incur operating losses for the foreseeable future as we commercially launch YUTREPIA and advance our other product candidates through clinical trials, seek regulatory approval and pursue commercialization of any approved product candidates. The future viability of our company will depend on our ability to fund future operations and capital requirements with revenue from YUTREPIA and, if necessary, additional capital from external financing.

Previous wording

We are subject to risks and uncertainties common to early-stage companies in the biotechnology industry, including, but not limited to, development by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with government regulations, and the ability to secure additional capital to fund operations. We expect to incur significant expenses and may incur significant operating losses for the foreseeable future as we advance product candidates through clinical trials, seek regulatory approval and pursue commercialization of any approved product candidates. We do not expect to generate significant revenue unless and until we are able to obtain marketing approval for and successfully commercialize one or more of our product candidates. In addition, if we obtain marketing approval for any of our product candidates, we would incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution. These efforts require significant amounts of capital, adequate personnel and infrastructure, and extensive compliance-reporting capabilities. Even if our development efforts are successful, it is uncertain when, if ever, we will realize significant revenue from product sales. The future viability of our company will depend on our ability to fund future operations and capital requirements with additional capital from external financing. We may seek additional funding through public or private financings, debt financing or collaboration. Our inability to obtain funding, when needed, would have a negative impact on our financial condition and ability to pursue our business strategies.

We expect to incur significant expenses and may incur significant operating losses for the foreseeable future as we commercially launch YUTREPIA and advance our other product candidates through clinical trials, seek regulatory approval and pursue commercialization of any approved product candidates. We do not expect to generate significant revenue unless we are able to maintain FDA approval for and successfully commercialize YUTREPIA or obtain marketing approval for and successfully commercialize one or more of our other product candidates. United Therapeutics is seeking injunctive relief that would require us to remove YUTREPIA from the market or remove one or both of PAH and PH-ILD from its label, which would limit our ability to commercialize YUTREPIA, if we are able to do so at all. Even with marketing approval for YUTREPIA and any of our other product candidates, we would incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution.

Previous wording

We have a history of losses and our future profitability remains uncertain. Our net losses and significant cash used in operating activities have raised substantial doubt regarding our ability to continue as a going concern.

Current wording

We have a history of losses and our future profitability remains uncertain.

Previous wording

We have incurred net losses of $38.4 million during the three months ended March 31, 2025, and $128.3 million and $78.5 million during the years ended December 31, 2024 and 2023, respectively. We also had negative operating cash flows for each of these periods. As of March 31, 2025, we had an accumulated deficit of $595.8 million.

Current wording

We have incurred net losses of $79.9 million during the six months ended June 30, 2025, and $128.3 million and $78.5 million during the years ended December 31, 2024 and 2023, respectively. We also had negative operating cash flows for each of these periods. As of June 30, 2025, we had an accumulated deficit of $637.3 million.

Previous wording

Since our incorporation, we have invested heavily in the development of our product candidates and technologies, as well as in recruiting management and scientific personnel. To date, we have not commenced the commercialization of our product candidates and all of our revenue has been derived from up-front fees and milestone payments made to us in connection with licensing and collaboration arrangements we have entered into and the Promotion Agreement, under which we share in the profit derived from the sale of Treprostinil Injection in the United States. These up-front fees and milestone payments have been, and combined with revenue generated from Treprostinil Injection may continue to be, insufficient to match our operating expenses. We expect to continue to devote substantial financial and other resources to the clinical development of our product candidates and, as a result, must generate significant revenue to achieve and maintain profitability. We may continue to incur losses and negative cash flow and may never transition to profitability or positive cash flow. These factors raise substantial doubt about our ability to continue as a going concern and to satisfy our estimated liquidity needs for one year from the issuance of the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q. Accordingly, we will require additional funding over the next twelve months to continue our operations and maintain compliance with debt covenants, and could be required to delay, reduce, or eliminate research and development programs, product portfolio expansion, or commercialization efforts, which could adversely affect our business prospects, or potentially force us to cease operations.

Previous wording

We expect that we will need further financing for our existing business and future growth, which may not be available on acceptable terms, if at all. Failure to obtain funding on acceptable terms and on a timely basis may require us to curtail, delay or discontinue our product development efforts or other operations. The failure to obtain further financing may also prevent us from capitalizing on other potential product candidates or indications which may be more profitable than YUTREPIA and/or L606 or for which there may be a greater likelihood of success.

Current wording

In the event revenues from YUTREPIA are insufficient to support our future capital needs, we expect that we would need further financing for our existing business and future growth, which may not be available on acceptable terms, if at all. Failure to obtain funding, if needed, on acceptable terms and on a timely basis may require us to curtail, delay or discontinue our product commercialization and development efforts or other operations. The failure to obtain further financing may also prevent us from capitalizing on other potential product candidates or indications which may be more profitable than YUTREPIA and/or L606 or for which there may be a greater likelihood of success.

Previous wording

We expect that we will need to raise additional funds to meet our future funding requirements for the continued research, development and commercialization of our product candidates and technology. Our future funding requirements will be heavily determined by the timing of the potential commercialization of YUTREPIA and the resources needed to support development of our product candidates. In the event that funds generated from our operations are insufficient to fund our future growth, we may raise additional funds through the issuance of equity or debt securities or by borrowing from banks or other financial institutions. We cannot assure you that we will be able to obtain such additional financing on terms that are acceptable to us, or at all. Global and local economic conditions could negatively affect our ability to raise funds. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms of such securities may include liquidation or other preferences that adversely affect your rights as a stockholder. Such financing, even if obtained, may be accompanied by restrictive covenants that may, among others, limit our ability to pay dividends or require us to seek consent for payment of dividends, or restrict our freedom to operate our business by requiring consent for certain actions.

If we fail to obtain financing on terms that are favorable to us, we will not be able to implement our growth plans, and we may be required to significantly curtail, delay or discontinue one or more of our research, development or manufacturing programs or the commercialization of any approved product. Furthermore, if we fail to obtain additional financing on terms that are acceptable to us, we may forgo or delay the pursuit of opportunities presented by other potential product candidates or indications that may later prove to have greater commercial potential than the product candidates and indications that we have chosen to pursue.

Our management has broad discretion in the application of such proceeds and could spend the proceeds in ways that do not improve our results of operations or enhance the value of our equity. The failure by our management to apply these funds effectively could result in financial losses that could have a material adverse effect on our business, diminish cash flows available to service our obligations to HCR, cause the value of our equity to decline and delay the development of our product candidates. Pending their use, we may invest such proceeds in short-term, investment-grade, interest-bearing securities, which may not yield favorable returns.

Our ability to continue our operations and manage our potential future growth depends on our ability to hire and retain suitably skilled and qualified employees, including those in senior management, in the long-term. Due to the specialized nature of our work, there is a limited supply of suitable candidates. We compete with other biotechnology and pharmaceutical companies, educational and research institutions and government entities, among others, for research, technical, clinical and sales and marketing personnel. In addition, in order to manage our potential future growth effectively, we will need to improve our financial controls and systems and, as necessary, recruit sales, marketing, managerial and finance personnel. The loss of the services of members of our sales team could seriously harm our ability to successfully implement our business strategy. If we are unable to attract and retain skilled personnel, including in particular Roger Jeffs, our Chief Executive Officer, we may not be able to successfully implement the tasks necessary to further develop and commercialize our product candidates and, accordingly, our business and prospects may be materially and adversely affected.

Under Section 382 of the Internal Revenue Code of 1986, as amended (the “IRC”), if a corporation undergoes an “ownership change”, generally defined as a greater than 50.0% change (by value) in its equity ownership over a three-year period, the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes, such as research tax credits, to offset its post-change income may be limited. Given our many financings and other equity issuances, including our September 2024 public equity offering, our September 2024 Private Placement, our January 2024 Private Placement, our December 2023 public equity offering, our December 2023 private placement, our April 2022 public equity offering, our 2021 private placement, the closing of the RareGen acquisition in November 2020, our July 2020 public equity offering, our December 2019 private placement, issuances under our prior at-the-market facility, our March 2019 follow-on equity offering and our July 2018 initial public offering, as well as other past transactions, we may have already triggered an “ownership change” limitation. We have not completed a formal study to determine if any “ownership changes” within the meaning of IRC Section 382 have occurred. If such “ownership changes” have occurred, and if we earn net taxable income, our ability to use our net operating loss carryforwards and research and development tax credits generated since inception to offset U.S. federal taxable income may be subject to limitations, which could potentially result in increased future tax liability to us and could require us to pay U.S. federal income taxes earlier than would be required if such limitations were not in effect. Similar rules and limitations may apply for state income tax purposes.

The tax regimes to which we are subject or under which we operate are unsettled and may be subject to significant change. Following the change in U.S. administration, there is uncertainty regarding future legislative and regulatory changes and policies related to matters such as taxation and importation, and any such proposed or enacted regulations by the current or a future U.S. administration, Congress, or taxing authorities in other jurisdictions could materially affect our tax obligations and operating results.

activities conducted outside the United States. In January 2024, the U.S. House of Representatives passed the Tax Relief for American Families and Workers Act, which would retroactively repeal for 2022 and 2023, and defer until 2026, the requirement to capitalize research and development expenditures for research activities conducted in the United States. Uncertainty exists as to whether the bill will be enacted into law. In addition, the IRA, among other things, included a new 15% alternative minimum tax on the adjusted financial statement income of certain large corporations for tax years beginning in 2023. To the extent that such changes have a negative impact on us, including as a result of related uncertainty, these changes could adversely impact our business, results of operations and financial position.

Current wording

For example, beginning in 2022, the Tax Cuts and Jobs Act of 2017 eliminated the option to deduct research and development expenditures in the year incurred and instead requires taxpayers to capitalize and subsequently amortize such expenditures over five years for research activities conducted in the United States and over 15 years for research activities conducted outside the United States. The One Big Beautiful Bill Act (“OBBBA”)reinstates the option to deduct domestic research and development expenditures in the year incurred, commencing with tax years beginning after December 31, 2024. Foreign research and development expenditures remain subject to the 15-year capitalization and amortization requirement. The OBBBA also includes other significant provisions, including tax cut extensions and modifications to the international tax framework. While we continue to evaluate the impact of these legislative changes as additional guidance becomes available, uncertainty remains regarding the timing and interpretation by tax authorities in affected jurisdictions. In addition, the Inflation Reduction Act (“IRA”), among other things, included a new 15% alternative minimum tax on the adjusted financial statement income of certain large corporations for tax years beginning in 2023. To the extent that such changes have a negative impact on us, including as a result of related uncertainty, these changes could adversely impact our business, results of operations and financial position.

We are a late-stage clinical biopharmaceutical company with no approved products and no historical revenue from the sale of our own products, which may make it difficult for you to evaluate our business, financial condition and prospects.

Current wording

We are a late-stage clinical biopharmaceutical company with only one approved product that was only recently approved by the FDA, which may make it difficult for you to evaluate our business, financial condition and prospects.

Previous wording

We are a late-stage clinical biopharmaceutical company with no history of commercial operations upon which you can evaluate our prospects other than the activities we have undertaken with respect to the Promotion Agreement with Sandoz. Drug product development involves a substantial degree of uncertainty. Our operations to date have been limited to engaging in promotional and nonpromotional activities under the Promotion Agreement with Sandoz, developing our PRINT technology, undertaking preclinical studies and clinical trials for our product candidates and collaborating with pharmaceutical companies, including GSK, to expand the applications for our PRINT technology through licensing as well as joint product development arrangements. We have not obtained final marketing approval for any of our product candidates and, accordingly, have not demonstrated an ability to generate revenue from our own pharmaceutical products or successfully overcome the risks and uncertainties frequently encountered by companies undertaking drug product development. Consequently, your ability to assess our business, financial condition and prospects may be significantly limited. Further, the net losses that we incur may fluctuate significantly from quarter-to-quarter and year-to-year, such that a period-to-period comparison of our results of operations may not be a good indication of our future performance. Other unanticipated costs may also arise in connection with the development of our product candidates and commercialization of any approved products.

Current wording

We are a late-stage clinical biopharmaceutical company with only one approved product, which was approved by the FDA in May 2025 and launched in June 2025.

The commercial success of Treprostinil Injection may also be impacted by increasing generic competition which may result in declining prices for Treprostinil Injection.

Previous wording

We are seeking to work with third parties to develop or procure other pumps that can be used to administer Treprostinil Injection in the future. For example, we have entered into a Pump Development Agreement with Sandoz and Mainbridge to develop a new pump that can be used to administer Treprostinil Injection in the future. Such pumps will require FDA 510(k) clearance before they can be sold. There is no guarantee that we or our partners will receive FDA 510(k) clearance for any such pumps or, even if they do receive FDA 510(k) clearance for any such pumps, that they will do so in a timely manner. For example, we have still not submitted a 510(k) clearance application for a pump under our agreement with Sandoz and Mainbridge and are currently uncertain when, if ever, such a 510(k) clearance application will be submitted. If we are unable to identify, develop and obtain any required FDA clearance for new pumps for the subcutaneous administration of Treprostinil Injection prior to the unavailability of the CADD-MS 3 infusion pump, we may no longer be able to serve patients with Treprostinil Injection through the subcutaneous route of administration.

In the New Hatch-Waxman Litigation, United Therapeutics is asserting that the Company infringes U.S. Patent No. 11,826,327 (the “‘327 Patent”), entitled “Treatment for Interstitial Lung Disease.” In February 2024, United Therapeutics filed a motion seeking a preliminary injunction to prevent us from manufacturing, marketing, storing, importing, distributing, offering for sale, and/or selling YUTREPIA for the treatment of PH-ILD. The motion for a preliminary injunction was denied in May 2024, and trial is currently scheduled for June 2025.

Current wording

In connection with an amendment to our NDA filed in July 2023 to add PH-ILD as an indication for YUTREPIA, we provided a new notice of the paragraph IV certification to United Therapeutics as the owner of the patents that are the subject of the certification to which the NDA for YUTREPIA refers. As a result, in September 2023, United Therapeutics filed a complaint for patent infringement against us in the U.S. District Court for the District of Delaware (Case No. 1:23-cv-00975-RGA) (the “’327 Patent Litigation”). In the ‘327 Patent Litigation, United Therapeutics is asserting that the Company infringes U.S. Patent No. 11,826,327 (the “‘327 Patent”), entitled “Treatment for Interstitial Lung Disease,” and is seeking injunctive relief that would require YUTREPIA to be removed from the market and monetary damages. Trial was held in June 2025. The outcome of the trial is uncertain, which creates risk regarding our ability to continue commercializing YUTREPIA, because an adverse decision could result in immediate injunctive or other relief, which could materially disrupt our business. In the event United Therapeutics prevails, the Court may order that the FDA withdraw its approval for YUTREPIA or that the PH-ILD indication be removed from YUTREPIA’s label.

Previous wording

In addition, United Therapeutics may seek to assert newly issued patents against us, including U.S. Patent Number 11,723,887, and may seek to enjoin the FDA from granting final approval to YUTREPIA or enjoin us from launching YUTREPIA through one or more additional legal proceedings.

Current wording

United Therapeutics may in the future seek to assert additional or newly issued patents against us, including U.S. Patent Number 11,723,887, and may seek to enjoin us from selling YUTREPIA for one or more indications through one or more additional legal proceedings.

Previous wording

As a result of this litigation instituted to date and potential litigation that may be instituted in the future, final FDA approval of YUTREPIA for PAH and/or PH-ILD may be further delayed even past the PDUFA goal date of May 24, 2025. Further, even if we receive FDA approval for YUTREPIA, we may be subject to significant delay and incur substantial additional costs in litigation before we are able to commercialize YUTREPIA, if at all. In addition, if United Therapeutics is successful in any of its claims that it has brought to date or any claims it may bring in the future, we may be unable to commercialize YUTREPIA for the treatment of one or more indications or at all until the expiration of the applicable United Therapeutics patents, which could materially harm our business. For example, in the event United Therapeutics prevails with respect to its claims regarding the ‘327 Patent, it is possible that an injunction could be issued, preventing the FDA from granting final approval for YUTREPIA for PH-ILD or forcing the FDA to revoke any prior approval for YUTREPIA for PH-ILD. Also, although United Therapeutics’ initial requests for injunctive relief have been denied, if United Therapeutics is successful in obtaining a preliminary injunction or temporary restraining order in the New Hatch-Waxman Litigation or the New FDA Litigation, we could be limited to commercializing YUTREPIA only for the PAH indication for an extended time period.

Current wording

If United Therapeutics is successful in any of its claims that it has brought to date or any claims it may bring in the future, we may be unable to commercialize YUTREPIA for the treatment of one or more indications or at all until the expiration of the applicable United Therapeutics patents, which could materially harm our business. For example, in the event United Therapeutics prevails with respect to its claims regarding the ‘327 Patent, it is possible that an injunction could be issued, forcing the FDA to withdraw the approval for YUTREPIA, at least until PH-ILD has been removed from the label, or restricting our ability to market and sell YUTREPIA for one or both indications for which it has been approved. In such event, we could be prevented from commercializing YUTREPIA for one or more indications for an extended time period.

Previous wording

In December 2021, United Therapeutics filed a complaint in the Superior Court in Durham County, North Carolina, alleging that we and a former United Therapeutics employee who later joined us as an employee many years after terminating his employment with United Therapeutics (the “Former Employee”) conspired to misappropriate certain trade secrets of United Therapeutics and engaged in unfair or deceptive trade practices. In January 2024, the Former Employee filed a motion for summary judgment on all claims, but the motion was denied in July 2024. In addition, in July 2024, the Company filed a motion for summary judgment with respect to all claims. Briefing on the Company’s motion is complete and a hearing was held in December 2024. The motion remains pending.

Both we and the Former Employee filed motions for summary judgment on all claims, but the motions were denied. In the event United Therapeutics prevails with respect to its trade secret claims, it could seek injunctive relief and substantial monetary damages.

Previous wording

In May 2024, United Therapeutics filed a second complaint in the Superior Court in Durham County, North Carolina, against the Former Employee, alleging that he breached prior employment agreements with United Therapeutics by failing to assign to United Therapeutics his interest in patents obtained by the Company that relied upon or benefitted from certain inventions, discoveries, materials, authorship, derivatives and results developed by the Former Employee while he was employed by United Therapeutics. The Company was also named as a defendant in this new lawsuit. As part of the lawsuit, United Therapeutics alleges that the Former Employee misappropriated certain intellectual property of United Therapeutics which led to the development of YUTREPIA. The complaint also seeks declaratory judgement such that all right, title and interest in and to any patentable or unpatentable inventions, discoveries, and ideas made or conceived by the Former Employee while employed by the Company should be assigned and transferred to United Therapeutics because they involved the use of United Therapeutics’ confidential information. In July 2024, the Company filed a motion to dismiss all claims. Briefing on the motion is complete and a hearing was held in December 2024. The motion remains pending.

If United Therapeutics prevails with respect to its breach of contract claims, we could be required to assign an interest in certain of our intellectual property, including our ‘494 patent, to United Therapeutics, in which case we would not be able to prevent United Therapeutics from practicing our proprietary methods.

Previous wording

If we are found to infringe, misappropriate or otherwise violate any of United Therapeutics’ intellectual property rights, we could be required to obtain a license from United Therapeutics to continue developing and marketing YUTREPIA. However, we may not be able to obtain any required license on commercially reasonable terms or at all. We could be found liable for monetary damages, including treble damages and attorneys’ fees if we are found to have willfully infringed a patent or to have misappropriated a trade secret of United Therapeutics. In addition, we may be forced to redesign YUTREPIA to avoid infringement.

We could be found liable for monetary damages, including treble damages and attorneys’ fees if we are found to have willfully infringed a patent or to have misappropriated a trade secret of United Therapeutics. In addition, we may be forced to refrain from promoting YUTREPIA for one or more indications, or altogether, until the applicable patent(s) expire.

Previous wording

We face significant competition from large pharmaceutical companies, among others, in developing our products and in gaining regulatory approval to bring them to market in time to achieve commercial success, and our operating results will suffer if we are unable to compete effectively.

Current wording

We face significant competition from large pharmaceutical companies, among others, in developing and commercializing our products and product candidates, and our operating results will suffer if we are unable to compete effectively, including if one or more such products have a superior product profile to YUTREPIA and/or L606.

Previous wording

Any new drug product that competes with a prior approved drug product must demonstrate advantages in safety, efficacy, tolerability or convenience in order to overcome price competition and to be commercially successful. Our products, if and when approved, are expected to face competition from drug products that are already on the market, as well as those in our competitors’ development pipelines. We expect that our lead program, YUTREPIA, an inhaled treprostinil therapy for the treatment of PAH and PH-ILD, and L606, a nebulized, liposomal formulation of treprostinil for treatment of PAH and PH-ILD, will face competition from the following inhaled prostacyclin analog therapies that are either currently marketed or in clinical development:

YUTREPIA faces, and our product candidates if approved will face, competition from drug products that are already on the market, as well as those in our competitors’ development pipelines. We expect that YUTREPIA, an inhaled treprostinil therapy for the treatment of PAH and PH-ILD, and L606, a nebulized, liposomal formulation of treprostinil for treatment of PAH and PH-ILD, will face competition from the following inhaled prostacyclin analog therapies that are either currently marketed or in clinical development:

Previous wording

administered parenterally, both of which are marketed by United Therapeutics. Branded pharmaceutical companies such as United Therapeutics continue to defend their products vigorously through, among other actions, life cycle management, marketing agreements with third-party payors, pharmacy benefits managers and generic manufacturers. These actions add increased competition in the generic pharmaceutical industry, including competition for Treprostinil Injection.

Current wording

In addition to these other inhaled treprostinil therapies, we expect that YUTREPIA and L606 will also face competition from other treprostinil-based drugs, including Orenitram, which is administered orally, and Remodulin, which is administered parenterally, both of which are marketed by United Therapeutics. Branded pharmaceutical companies such as United Therapeutics continue to defend their products vigorously through, among other actions, life cycle management, marketing agreements with third-party payors, pharmacy benefits managers and generic manufacturers. These actions add increased competition in the generic pharmaceutical industry, including competition for Treprostinil Injection.

Previous wording

We are also aware of several other agents in clinical development that are exploring mechanisms of action which, if approved, could impact the standard of care for treating PAH and/or PH-ILD in the United States, including programs from Gossamer Bio, Inc., Cereno Scientific, Novartis AG, and Forsee Pharmaceuticals among others.

Previous wording

granted marketing approval and/or regulatory exclusivity before we are able to obtain FDA approval for our product candidate. In that case, as stated above, there is the possibility that such a competitor would be able to prevent us from obtaining approval of and marketing our product candidate until the expiration of the competitor’s term of FDA regulatory exclusivity, which could be a term of three years for so-called New Clinical Investigation exclusivity, or could conceivably be for longer periods of time if the competitor is successful in being granted other forms of FDA regulatory exclusivity which might include, for example, Orphan Disease Designation exclusivity (seven years), New Chemical Entity exclusivity (five years), or Pediatric exclusivity (six months beyond other existing exclusivities or patent terms). For example, United Therapeutics was awarded New Clinical Investigation exclusivity for Tyvaso DPI, which will expire in May 2025. As a result, the FDA will be unable to approve YUTREPIA until after the exclusivity expires in May 2025. In the event United Therapeutics sought and was able to obtain one or more other regulatory exclusivities with respect to Tyvaso DPI, it could further significantly delay our ability to obtain final approval for YUTREPIA. Even if the FDA does not recognize any new regulatory exclusivity for United Therapeutics, United Therapeutics could challenge the FDA’s decision and seek an injunction to prevent approval of YUTREPIA in one or more indications until such challenge has been decided.

Current wording

There are a number of competitors seeking marketing approval and/or regulatory exclusivity with respect to products that are or would be competitive to L606. Thus, we face the risk that one of our competitors will be granted marketing approval and/or regulatory exclusivity before we are able to obtain FDA approval for L606. In that case, as stated above, there is the possibility that such a competitor would be able to prevent us from obtaining approval of and marketing our product candidate until the expiration of the competitor’s term of FDA regulatory exclusivity, which could be a term of three years for so-called New Clinical Investigation exclusivity, or could conceivably be for longer periods of time if the competitor is successful in being granted other forms of FDA regulatory exclusivity which might include, for example, Orphan Disease Designation exclusivity (seven years), New Chemical Entity exclusivity (five years), or Pediatric exclusivity (six months beyond other existing exclusivities or patent terms).

Previous wording

One or more products that are competitive with YUTREPIA could also obtain approval for additional indications or broader conditions of use. These additional indications and broader conditions of use could be protected by one or more patents or regulatory exclusivities, preventing YUTREPIA from obtaining approval for the same indications or conditions of use. For instance, if Liquidia is prevented from launching or selling YUTREPIA for the treatment of PH-ILD in connection with the patent litigation related to the ‘327 patent or the lawsuit that United Therapeutics filed against the FDA, Tyvaso and Tyvaso DPI would have broader labels than YUTREPIA. In addition, United Therapeutics is currently studying Tyvaso for the treatment of idiopathic pulmonary fibrosis, an indication for which it has received an orphan drug designation. Thus, even if YUTREPIA is approved, such competitive products could have a broader label than the initial label for YUTREPIA. If YUTREPIA has a narrower label than other competitive products, it may affect our ability to compete with such products.

We are currently focused on developing drug products that can be approved under abbreviated regulatory pathways in the United States, such as the 505(b)(2) regulatory pathway, which allows us to rely on existing knowledge of the safety and efficacy of the relevant reference listed drugs to support our applications for approval in the United States. While we believe that it will be less difficult for us to convince physicians, patients and other members of the medical community to accept and use our drug products as compared to entirely new drugs, our drug products may nonetheless fail to gain sufficient market acceptance by physicians, patients, other healthcare providers and third-party payors. If any of our drug products fail to achieve sufficient market acceptance or third-party payor coverage, we may not be able to generate sufficient revenue to become profitable. The degree of market acceptance and third-party payor coverage of our drug products, if and when they are approved for commercial sale, will depend on a number of factors, including but not limited to:

With the acquisition of Liquidia PAH, we acquired a sales force to market generic treprostinil in accordance with the Promotion Agreement. In addition, during 2023, we significantly increased the size of our sales force in anticipation of a potential launch of YUTREPIA. However, if we experience continued delays in the approval of YUTREPIA, we may be unable to retain our sales force. Moreover, we cannot assure you that we will be successful in further building or effectively managing our marketing and sales capabilities or be able to do so in a cost-effective manner. In addition, we may enter into collaboration arrangements with third parties to market our drug products. We may face significant competition for collaborators. In addition, collaboration arrangements may be time-consuming to negotiate and document. We cannot assure you that we will be able to negotiate
