Business Description

1. Business Description of the Business We are a biopharmaceutical company driven by science and compassion to revolutionize care for patients with challenging respiratory and vascular diseases such as pulmonary arterial hypertension (“PAH”) and pulmonary hypertension associated with interstitial lung disease (“PH-ILD”). We operate through our wholly owned operating subsidiaries, Liquidia Technologies, Inc. and Liquidia PAH, LLC, formerly known as RareGen. We currently generate revenue through the sale of YUTREPIA (treprostinil) inhalation powder (“YUTREPIA”) and pursuant to a promotion agreement with Sandoz Inc. (“Sandoz”), dated as of August 1, 2018, as amended (the “Promotion Agreement”), under which we share profit derived from the sale of Sandoz’s generic treprostinil injection (“Treprostinil Injection”) in the United States. We employ a targeted commercial field force calling on healthcare providers involved in the treatment of PAH and PH-ILD in the United States, as well as key stakeholders involved in the distribution and reimbursement of medicines to treat these patients. YUTREPIA is an inhaled dry powder formulation of treprostinil designed with our proprietary PRINT technology, a particle engineering platform that enables precise production of uniform drug particles, to improve the therapeutic profile of treprostinil by enhancing deep lung delivery while using a convenient, low effort dry-powder inhaler (“DPI”) and by achieving higher dose levels than the labeled doses of other marketed inhaled treprostinil therapies. YUTREPIA was approved by the U.S. Food and Drug Administration (“FDA”) in May 2025 for the treatment of both PAH and PH-ILD, and began commercialization in June 2025. Treprostinil Injection is a fully-substitutable generic treprostinil for parenteral administration in the United States. We have the exclusive rights to conduct commercial activities for Treprostinil Injection and work jointly with Sandoz on commercial strategy for the product. Sandoz retains all other rights in and to Treprostinil Injection and holds the Abbreviated New Drug Application (“ANDA”) for Treprostinil Injection. We also conduct research, development and manufacturing of novel products by applying our subject matter expertise in respiratory and vascular diseases. For example, we are currently developing L606, an investigational, liposomal formulation of treprostinil, which we licensed from Pharmosa Biopharm Inc. (“Pharmosa”), that is administered twice-daily with a short-duration next-generation nebulizer. L606 is currently being evaluated in an open-label study in the United States for treatment of PAH and PH-ILD, and we have initiated a worldwide-placebo-controlled pivotal study for the treatment of PH-ILD. We are also planning to conduct clinical studies to evaluate YUTREPIA for the treatment of pulmonary hypertension associated with chronic obstructive pulmonary disease (“PH-COPD”), idiopathic pulmonary fibrosis (“IPF”), progressive pulmonary fibrosis (“PPF”) and Raynaud’s phenomenon associated with systemic sclerosis (“SSc-RP”). Risks and Uncertainties We are subject to risks and uncertainties common to companies in the biotechnology industry, including, but not limited to, development by competitors of new technological innovations, dependence on third parties and key personnel, protection of proprietary technology, compliance with government regulations, and the ability to secure additional capital to fund operations. We operate in a dynamic and highly competitive industry and believe that changes in any of the following areas could have a material adverse effect on our future financial position, results of operations, or cash flows: advances and trends in new technologies and industry standards; results of clinical trials; regulatory approval, market acceptance and third- party payor coverage for our products; development of sales channels; certain strategic relationships; litigation or claims against us, including claims related to intellectual property, product, regulatory, or other matters; and our ability to attract and retain employees necessary to support our growth. The current global macro-economic environment is volatile, which may result in supply chain constraints and elevated rates of inflation. We rely on single source manufacturers and suppliers for the supply of our products and product candidates, adding to the manufacturing risks we face.…
