RESEARCH TRIANGLE PARK, NC, March 11, 2020 – Liquidia Technologies, Inc. (Nasdaq: LQDA) (“Liquidia” or the “Company”), a late-stage clinical biopharmaceutical company focused on the development and commercialization of novel products utilizing its proprietary PRINT® technology, today reported financial results for the fourth quarter and full-year ended December 31, 2019, and provided a corporate update.

“We are pleased to have submitted our NDA for LIQ861, an important milestone in our continued evolution towards becoming a fully-integrated, commercial biopharmaceutical company. We were also pleased to raise additional equity capital through a private placement and ATM sales during the fourth quarter. We look forward to continuing to advance our pipeline based upon our PRINT technology to bring meaningful benefits to patients,” stated Neal Fowler, Liquidia’s Chief Executive Officer.

Corporate Update

Based upon the favorable results of the pivotal Phase 3 INSPIRE trial and pharmacokinetic studies in healthy volunteers, the Company submitted an NDA for LIQ861 to the U.S. Food and Drug Administration (FDA) on January 24, 2020 under the 505(b)(2) regulatory pathway. As previously reported, the safety and tolerability profile of LIQ861, the primary endpoint of the INSPIRE trial, was observed to be favorable. Also, as previously reported, a high rate of sustained treatment benefit across certain exploratory endpoints was observed, including the maintenance or improvement of New York Heart Association (NYHA) functional class in more than 90% of all patients enrolled in the trial who completed two months of treatment. As recently reported at the 14th Annual Pulmonary Vascular Research Institute (PVRI) Conference, results of a pharmacokinetic study in healthy volunteers have also demonstrated that treprostinil exposure from a 79.5 mcg dose of LIQ861 is comparable to that of nine breaths of Tyvaso, the reference listed drug.

Most patients from INSPIRE continue to receive LIQ861 in the extension study, including several patients with at least 18 months of treatment. The safety and tolerability profile of LIQ861 in this extension study remains consistent with the results seen in the INSPIRE trial. In addition, a clinical study has been initiated in patients with pulmonary arterial hypertension at certain investigational sites in Europe to characterize the hemodynamic dose-response relationship to LIQ861.

The Company continues to conduct Phase 2-enabling toxicology studies for LIQ865, a proprietary formulation of bupivacaine, a non-opioid anesthetic, targeting local post-operative pain relief for three to five days following a single administration. Results of the ongoing toxicology work are expected during the second half of 2020, and, subject to the availability of capital, the Company intends to determine next steps with regard to the clinical development program for LIQ865 following a review of all toxicology results. Additionally, the Company has recently initiated a pre-clinical program to develop an inhaled product leveraging the benefits of PRINT technology to engineer particles with precise, uniform, aerodynamic size and shape for deep lung delivery.

In December 2019, the Company completed a private placement of common stock, resulting in gross proceeds of $22.4 million. Additionally, the Company raised gross proceeds of $8.4 million through the sale of common stock pursuant to the Company's “at-the-market” (ATM) equity issuance facility during the fourth quarter.

Fourth Quarter 2019 Financial Results

Revenues for the three months ended December 31, 2019 were $0, compared to $0.6 million for the three months ended December 31, 2018. The decrease in revenues was due to the full recognition during the second quarter of 2019 of $8.1 million of deferred revenue from the Company's collaboration with GlaxoSmithKline plc (GSK) following the Company's determination that the earnings process related to the collaboration had been completed.

Research and development expenses for the fourth quarter of 2019 increased to $8.2 million from $8.0 million for the fourth quarter of 2018, primarily due to an increase in non-clinical expenses related to the LIQ865 program.

General and administrative expenses for the fourth quarter of 2019 increased to $5.8 million from $2.3 million for the fourth quarter of 2018, primarily due to increased commercial spending related to the LIQ861 program.

Loss from operations for the fourth quarter of 2019 increased to $14.0 million from $9.8 million for the fourth quarter of 2018, primarily due to an increase in commercial expenses related to the LIQ861 program as well as an increase in non-clinical expenses related to the LIQ865 program.

Interest income was $0.1 million for the fourth quarter of 2019, compared with $0.2 million for the fourth quarter of 2018, reflecting a lower average cash balance during the fourth quarter of 2019.

Interest expense was $0.6 million for the fourth quarter of 2019, compared with $0.2 million for the fourth quarter of 2018, reflecting a higher level of debt outstanding during the fourth quarter of 2019.

Net loss for the fourth quarter of 2019 increased to $14.5 million from $9.7 million for the fourth quarter of 2018, primarily due to an increase in commercial expenses related to the LIQ861 program as well as an increase in non-clinical expenses related to the LIQ865 program.

Cash and cash equivalents totaled $55.8 million at December 31, 2019 and reflect the completion of the Company's private placement and ATM sales that resulted in gross proceeds of $22.4 million and $8.4 million (net proceeds of $21.1 million and $8.2 million), respectively, during the fourth quarter of 2019. There were 28.2 million shares outstanding as of December 31, 2019.

Full Year 2019 Financial Results

Revenues for the year ended December 31, 2019 were $8.1 million, compared to $2.7 million for the year ended December 31, 2018. The increase in revenues was due to the full recognition in the second quarter of 2019 of $8.1 million of deferred revenue from the Company's collaboration with GSK following the Company's determination that the earnings process related to the collaboration had been completed.

Cost of sales for 2019 increased to $0.8 million from $0.1 million for 2018 due to the amortization of the deferred sublicense payments that were previously paid to the University of North Carolina at Chapel Hill related to the Company’s collaboration with GSK following the Company’s determination that the earnings process related to the collaboration has been completed.

Research and development (R&D) expenses for 2019 increased to $40.5 million from $28.7 million for 2018, primarily due to an increase in expenses related to the LIQ861 clinical program as well an increase in non-clinical expenses related to the LIQ865 program.

General and administrative expenses for 2019 increased to $13.6 million from $8.8 million for 2018, primarily due to increased commercial spending related to the LIQ861 program.

Loss from operations for 2019 increased to $46.8 million from $34.9 million for 2018, primarily due to an increase in expenses related to the LIQ861 program, including both R&D and commercial expenses, and an increase in non-clinical expenses related to the LIQ865 program, partially offset by the increase in revenues noted above.

Interest income was $0.6 million for 2019, compared with $0.3 million for 2018, reflecting a higher average cash balance in 2019.

Interest expense was $1.4 million for 2019, compared with $19.0 million for 2018, reflecting a lower level of debt during the year 2019 and the conversion of $27.4 million of convertible notes into shares of Series D preferred stock in February 2018.

Net loss for 2019 decreased to $47.6 million from $53.1 million for 2018, primarily due to a decrease in interest expense and an increase in revenues, which were partially offset by an increase in expenses related to the LIQ861 program, including both R&D and commercial expenses, as well as an increase in non-clinical expenses related to the LIQ865 program.
