• Clarified path to potential launch YUTREPIA upon resolution of litigation in late-2023 to mid-2024
• Fortified financial position through 2024
• Company to host webcast today at 8:30 a.m. ET

MORRISVILLE, N.C., March 16, 2023 (GLOBE NEWSWIRE) -- Liquidia Corporation (NASDAQ: LQDA) (�Liquidia� or the �Company�) today reported financial results for the full year ended December 31, 2022. The Company will host a webcast at 8:30 a.m. ET to discuss the 2022 financial results and provide a corporate update.

Roger Jeffs, Liquidia�s Chief Executive Officer, said: �We made notable strides toward unlocking the full potential of Liquidia in 2022. Our legal and patent wins were major achievements, clarifying the path to legal resolution. If approved, YUTREPIA will provide patients with pulmonary arterial hypertension (PAH) and pulmonary hypertension with interstitial lung disease (PH-ILD) with the option to receive a differentiated inhaled treprostinil product via a low-resistance dry powder inhaler. The ongoing open-label extension study continues to demonstrate the merits of YUTREPIA�s dosing flexibility and durability by attaining dosing levels that have not been achievable historically with Tyvaso�, thus enhancing the clinical ability to manage patients over time. Our revenue interest financing with HealthCare Royalty, one of the marquee royalty firms, provided significant non-dilutive capital to advance our platform goals. As an example, our recently announced partnership with Mainbridge Health Partners will advance a new subcutaneous infusion pump for Treprostinil Injection, a therapeutically equivalent and less expensive generic option. We look forward to continuing to unlock value in 2023.�

Corporate Updates

New leadership to prepare for commercialization. During the year, the Company hired key employees in the C-suite, in the sales force and in operational units to support the potential launch of YUTREPIA. The net impact added decades of combined experience in the development and commercialization of medicines to treat pulmonary hypertension between Chief Executive Officer Dr. Roger Jeffs, Chief Medical Officer Dr. Rajeev Saggar, Head of Sales Matt Snow, and Head of Medical Affairs Gareth Gwyn. Additionally, the Company established key commercial support functions to address all stakeholders and bolstered manufacturing teams to build commercial inventory in preparation for YUTREPIA�s potential final approval by the U.S. Food and Drug Administration (FDA).

Clarified path to legal resolution with key wins. The Company demonstrated in at least one legal forum that all of the claims in three patents asserted by United Therapeutics Corporation (UTC) are invalid or not infringed. If every decision in favor of Liquidia is affirmed on appeal by UTC, then Liquidia would be clear to seek final regulatory approval of YUTREPIA. The Company expects legal resolution in late 2023 or the first half of 2024.

As background, in 2020, UTC filed litigation in the United States District Court for the District of Delaware (District Court) under the Drug Price Competition and Patent Term Restoration Act (the Hatch-Waxman Litigation) alleging that Liquidia infringes U.S. Patent No. 9,593,066 (�066 Patent), U.S. Patent No. 10,716,793 (�793 Patent) and U.S. Patent No. 9,604,901 (�901 Patent). In parallel inter partes review (IPR) proceedings before the Patent Trial and Appeal Board (PTAB), the Company sought to invalidate the claims of the three asserted patents.

Briefing in appeal of Hatch-Waxman Litigation now complete. In August 2022, the District Court ruled in Liquidia�s favor with respect to the �066 Patent, finding that five of the six asserted claims of the '066 Patent are invalid and that the remaining asserted claim is not infringed by Liquidia. At the same time, the District Court found that all of the claims of the �793 Patent were valid and infringed by Liquidia based on the arguments that were presented by Liquidia in the Hatch-Waxman Litigation. Liquidia appealed the District Court�s decision with respect to the �793 Patent to the U.S. Court of Appeals for the Federal Circuit (Federal Circuit), and UTC appealed the District Court�s decision with respect to the �066 Patent to the Federal Circuit. Briefing is now complete and the parties are awaiting a scheduled date for oral argument, which Liquidia expects to occur during the second or third quarter of 2023.

�793 Patent deemed by PTAB to be invalid. In July 2022, the PTAB found in favor of Liquidia in the �793 IPR stating that all the claims of the �793 Patent have been shown to be unpatentable based on the preponderance of the evidence. In February 2023, the PTAB denied UTC �s request for a rehearing and, in so doing, reaffirmed and clarified its earlier decision that the claims of the �793 Patent are unpatentable. Based on earlier statements, UTC is expected to file an appeal of the PTAB decision to the Federal Circuit. Should the Federal Circuit affirm the PTAB�s decision, the PTAB�s decision would override any finding in the Hatch-Waxman Litigation that Liquidia has breached any valid claims of the �793 Patent.

�901 Patent deemed by PTAB to be invalid and then withdrawn by UTC from litigation. In December 2021, UTC stipulated that, based on the District Court�s construction of the claims in the �901 Patent, Liquidia does not infringe any of the asserted claims of that patent. UTC has not appealed any issues related to the �901 Patent, which has now been dropped from the Hatch-Waxman Litigation.

Increased long-term commitment to Treprostinil Injection market. To improve patients� access to subcutaneous infusion of treprostinil, the Company committed to alleviate the single-source dependence on the existing CADD-MS 3 system for subcutaneous delivery of Treprostinil Injection. In December, Liquidia, Sandoz and Mainbridge Health Partners established a collaboration to repurpose an FDA-approved infusion pump used for insulin with the objective of submitting a 510(k) in 2023. More recently, Liquidia and Sandoz have agreed to cooperate in taking actions designed to maintain the current inventory of CADD-MS3 pumps held at specialty pharmacies supporting PAH patients. Lastly, when establishing these new collaborations, Sandoz and Liquidia extended the term of the promotion agreement for Treprostinil Injection until December 31, 2032.

Fortified financial position through 2024. Liquidia continued to exercise financial discipline by focusing expenses and improving access to cash resources through a combination of a loan refinancing in January 2022, an underwritten public offering of equity in April 2022 and a revenue interest financing with HealthCare Royalty (HCRx) in January 2023 under which HCRx has agreed to pay�Liquidia an aggregate of up to $100 million upon certain events. To date, HCRx has funded $32.5 million, of which $22.4 million was used to satisfy in full and retire the then existing debt obligations to Silicon Valley Bank (SVB), with the excess proceeds less transaction costs of approximately $0.7 million funded to the Company. When combined with the revenue generated by sales of Treprostinil Injection, the Company is well-positioned to launch YUTREPIA within the expected time frame for legal resolution. As for the Company�s exposure to Silicon Valley Bank (SVB), 99% of funds were invested in a Blackrock mutual fund, and therefore, should not have been exposed by the events of the last week. As of March 14, 2023, substantially all cash and cash equivalents have been transferred out of SVB to an account held with an accredited financial institution.

Full Year 2022 Financial Results

Cash and cash equivalents totaled $93.3 million as of December 31, 2022.

Revenue was $15.9 million for the year ended December 31, 2022, compared with $12.9 million for the year ended December 31, 2021. During the year ended December 31, 2022, the profit split percentage we received under our Promotion Agreement with Sandoz Inc. was 50%, whereas during the year ended December 31, 2021, the profit split percentage decreased from 80% to 50% as a result of achievement of predetermined cumulative sales thresholds. This decrease in profit split percentage was offset by an increase in the number of units sold. Revenue in 2022 is net of $2.7 million in amortization of the contract acquisition costs associated with the Promotion Agreement.

Cost of revenue was $2.9 million for the year ended December 31, 2022, compared with $3.0 million for the year ended December 31, 2021. Cost of revenue related to the Promotion Agreement as noted above and included (i) the cost of employing a targeted sales force calling on physicians and hospital pharmacies involved in the treatment of PAH, as well as key stakeholders involved in the distribution and reimbursement of Treprostinil Injection and (ii) amortization of the intangible asset associated with the Promotion Agreement.

Research and development expenses were $19.4. million for the year ended December 31, 2022, compared with $20.5 million for the year ended December 31, 2021. The decrease of $1.1 million or 5% was primarily due to a $0.9 million decrease in personnel, consulting, and stock-based compensation expenses. During the year ended December 31, 2022, we incurred $7.0 million related to our YUTREPIA program compared to a total of $6.7 million during the year ended December 31, 2021.

General and administrative expenses were $32.4 million for the year ended December 31, 2022, compared with $23.1 million for the year ended December 31, 2021. The increase of $9.3 million or 40% was primarily due to a $4.2 million increase in commercial, marketing, and personnel expenses in preparation for the potential commercialization of YUTREPIA and a $3.1 million increase in stock-based compensation expense driven by an option modification charge recorded in the first quarter of 2022.

Other expenses, net were $2.2 million for the year ended December�31,�2022, compared with $0.8 million for the year ended December�31,�2021. The increase of $1.4 million was primarily due to a $1.0 million loss on extinguishment of debt related to the refinance of our long-term debt during January 2022 and a $1.6 million increase in interest expense due to a higher debt balance and higher interest rate on our debt from the A&R SVB LSA, offset by a $1.1 million increase in interest income from higher cash and cash equivalents balances.

Net loss for during the year ended December 31, 2022, was�$41.0 million, or�$0.67�per basic and diluted share, compared to a net loss of�$34.6 million, or�$0.70 per basic and diluted share, for the year ended December 31, 2021.

About YUTREPIA�(treprostinil) inhalation powder
YUTREPIA is an investigational, inhaled dry powder formulation of treprostinil delivered through a proven, convenient, palm-sized device. On November 5, 2021, the FDA issued a tentative approval for YUTREPIA, which is indicated for the treatment of pulmonary arterial hypertension (PAH) to improve exercise ability in adult patients with New York Heart Association (NYHA) Functional Class II-III symptoms. The FDA has confirmed that YUTREPIA may add the indication to treat pulmonary hypertension with interstitial lung disease (PH-ILD) without additional clinical studies. YUTREPIA was designed using Liquidia�s PRINT� technology, which enables the development of drug particles that are precise and uniform in size, shape, and composition, and that are engineered for optimal 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 na�ve to inhaled treprostinil or who are transitioning from Tyvaso� (nebulized treprostinil). YUTREPIA was previously referred to as LIQ861 in investigational studies.
