Recent Event On March 17, 2025, we entered into the Sixth Amendment to the HCR Agreement pursuant to which HCR made an additional $100.0 million available for funding under the second tranche. An additional $25.0 million from the second tranche was funded on March 17, 2025.
Added
Our net loss was $68.9 million, $128.3 million, and $78.5 million for the years ended December 31, 2025, 2024 and 2023, respectively. As of December 31, 2025, we had an accumulated deficit of $626.3 million.
Removed
An additional $50.0 million may be funded 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 an addition $25.0 million upon the mutual agreement of the parties after achieving aggregate net sales of YUTREPIA in excess of $100 million at any time on or prior to June 30, 2026.
Added
We have based this estimate on assumptions that may prove to be wrong, and we could be limited in our ability to continue to commercialize YUTREPIA and/or we could utilize our available capital resources sooner than we currently expect, which would have a material impact on our operations.
Removed
As consideration for the additional $25.0 million funded at closing, Liquidia has agreed to a fixed payment schedule that terminates in 2032. Payments on the last two tranches, when funded, would also follow a fixed payment schedule.
