Potential for final FDA approval of YUTREPIA (treprostinil) inhalation powder after expiration of regulatory exclusivity on May 23, 2025

On August 16, 2024, the United States Food and Drug Administration (FDA) granted tentative approval for YUTREPIA for the treatment of pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD) and simultaneously determined that Tyvaso DPI$(R)$ qualifies for a three-year New Clinical Investigation $(NCI)$ exclusivity for the chronic use of dry powder formulations of treprostinil for the approved indications. The NCI exclusivity will expire on May 23, 2025, after which the FDA may grant final approval of YUTREPIA.

Continuing to advance the pipeline of inhaled treprostinil in the clinic

The open-label ASCENT study evaluating the tolerability and titratability of YUTREPIA in patients with PH-ILD is nearing enrollment completion. Observations to date have demonstrated tolerability and titratability of YUTREPIA in PH-ILD patients that is consistent with observations from the prior INSPIRE study in PAH patients.

Liquidia continues to progress clinical studies of L606 (liposomal treprostinil) inhalation suspension, an investigational sustained-release formulation of treprostinil administered twice-daily with a next-generation nebulizer. The U.S. open-label safety study of 28 patients with PAH and PH-ILD remains ongoing. To date, participants have safely titrated to the study's maximum dose twice daily, which is comparable to 26-28 breaths of Tyvaso(R) administered four times per day. The FDA has confirmed that a single, placebo-controlled, global pivotal study in PH-ILD patients would support seeking approval to treat both PAH and PH-ILD patients.

Strengthened financial position by amending HCRx agreement to incrementally add up to $100 million

In March 2025, Liquidia entered into an amendment to its agreement with HCRx (HCR Agreement) to provide for up to an additional $100 million of financing in three tranches. Under the terms of the agreement, Liquidia received $25.0 million at closing with the potential to receive two additional tranches of funding: $50.0 million upon the first commercial sale of YUTREPIA following receipt of final FDA approval for the treatment of PAH and PH-ILD, so long as no injunction has been issued prohibiting Liquidia from commercializing YUTREPIA for either or both of PAH and PH-ILD, and $25.0 million upon the mutual agreement of the parties after achieving aggregate net sales of YUTREPIA in excess of $100 million any time on or prior to June 30, 2026.

Full Year 2024 Financial Results

Cash and cash equivalents totaled $176.5 million as of December 31, 2024, compared to $83.7 million as of December 31, 2023.

Revenue was $14.0 million for the year ended December 31, 2024, compared to $17.5 million for the year ended December 31, 2023. Revenue related primarily to the promotion agreement with Sandoz, Inc. pursuant to which we share profits from the sale of Treprostinil Injection in the United States (Promotion Agreement). The decrease of $3.5 million was primarily due to lower sales quantities, driven by limitations on the availability of pumps used to administer Treprostinil Injection subcutaneously. Sales quantities will continue to be impacted until alternative pumps are available.

Cost of revenue was $5.9 million for the year ended December 31, 2024, compared to $2.9 million for the year ended December 31, 2023. Cost of revenue related to the Promotion Agreement as noted above. The increase from the prior year was primarily due to our sales force expansion during the fourth quarter of 2023.

Research and development expenses were $47.8 million for the year ended December 31, 2024, compared to $43.2 million for the year ended December 31, 2023. The increase of $4.6 million or 11% was primarily due to (i) a $6.1 million increase in expenses related to our L606 program, (ii) a $5.3 million increase in expenses related to YUTREPIA research and development activities, including the ASCENT trial, (iii) a $5.1 million increase in personnel expenses (including stock-based compensation) related to increased headcount, and (iv) a $3.5 million upfront license fee due to Pharmosa for the exclusive license in Europe to develop and commercialize L606 recorded during the year ended December 31, 2024, offset by (i) $5.1 million lower commercial manufacturing expenses reflecting the impact of expensing YUTREPIA inventory costs in the prior year and (ii) a $10.0 million upfront license fee due to Pharmosa for the exclusive license in North America to develop and commercialize L606 recorded during the year ended December 31, 2023.

General and administrative expenses were $81.6 million for the year ended December 31, 2024, compared to $44.7 million for the year ended December 31, 2023. The increase of $36.9 million or 82% was primarily due to (i) a $19.7 million increase in personnel expenses (including stock-based compensation) driven by higher headcount and expansion of our sales force in the fourth quarter of 2023, (ii) a $7.9 million increase in legal fees related to our ongoing YUTREPIA-related litigation, and (iii) a $6.8 million increase in commercial expenses in preparation for the potential commercialization of YUTREPIA.

Total other expense, net was $9.1 million for the year ended December 31, 2024, compared to $5.1 million for the year ended December 31, 2023. The increase of $4.0 million was primarily driven by a $2.0 million increase in the net loss on extinguishment of debt resulting from the Fourth and Fifth Amendments to the HCR Agreement, which were executed in January 2024 and September 2024, respectively. Additionally, there was a $6.2 million increase in interest expense attributable to the higher borrowings under the HCR Agreement compared to the prior year and a $4.2 million increase in interest income attributable to higher money market balances.

Net loss for the year ended December 31, 2024, was $130.4 million or $1.66 per basic and diluted share, compared to a net loss of $78.5 million, or $1.21 per basic and diluted share, for the year ended December 31, 2023.

About YUTREPIA(TM) (treprostinil) Inhalation Powder

YUTREPIA is an investigational, inhaled dry-powder formulation of treprostinil delivered through a convenient, low-effort, palm-sized device. In August 2024, the FDA issued tentative approval of YUTREPIA for the PAH and PH-ILD indications. YUTREPIA was designed using Liquidia's PRINT(R) technology, which enables the development of drug particles that are precise and uniform in size, shape and composition, and that are engineered for enhanced deposition in the lung following oral inhalation. Liquidia has completed INSPIRE, or Investigation of the Safety and Pharmacology of Dry Powder Inhalation of Treprostinil, an open-label, multi-center phase 3 clinical study of YUTREPIA in patients diagnosed with PAH who are naïve to inhaled treprostinil or who are transitioning from Tyvaso(R) (nebulized treprostinil). YUTREPIA is currently being studied in the ASCENT trial, an Open-Label Prospective Multicenter Study to Evaluate Safety and Tolerability of Dry Powder Inhaled Treprostinil in Pulmonary Hypertension, to evaluate the safety and tolerability of YUTREPIA in PH-ILD patients. YUTREPIA was previously referred to as LIQ861 in investigational studies.

About L606 (liposomal treprostinil) Inhalation Suspension

L606 is an investigational, sustained-release formulation of treprostinil administered twice-daily with a next-generation nebulizer. The L606 suspension uses Pharmosa Biopharm's proprietary liposomal formulation to encapsulate treprostinil which can be released slowly at a controlled rate into the lung, enhancing drug exposure over an extended period of time. L606 is currently being evaluated in an open-label study in the United States for treatment of pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD) with a planned global pivotal placebo-controlled efficacy study for the treatment of PH-ILD.
