Item 8.01 Other Events.

On June 23, 2025, Liquidia Corporation, a Delaware corporation (the “Company”), issued a press release announcing the receipt of an additional $50.0 million under the Sixth Amendment to the Revenue Interest Financing Agreement, dated March 17, 2025 (the “HCR Agreement”), with HealthCare Royalty Partners IV, L.P. (“HCR”)

Under the HCR Agreement, an additional $50.0 million of funding is available to the Company after the first commercial sale of YUTREPIA following receipt of final FDA approval for the treatment of pulmonary arterial hypertension (“PAH”) and pulmonary hypertension associated with interstitial lung disease (“PH-ILD”), so long as no injunction has been issued prohibiting Liquidia from commercializing YUTREPIA™ (treprostinil) for either or both of PAH and PH-ILD (“Funding Condition”). The Funding Condition was satisfied when (i) on May 30, 2025, the U.S. District Court for the Middle District of North Carolina denied United Therapeutics Corporation’s request for a preliminary injunction and a temporary restraining order in its complaint filed against the Company and (ii) on June 2, 2025, the Company made its first commercial shipment of YUTREPIA inhalation powder. An additional funding of $25.0 million remains available under the HCR Agreement upon mutual agreement of HCR and the Company if the Company achieves aggregate net sales of YUTREPIA in excess of $100 million at any time on or prior to June 30, 2026.

A copy of the press release is filed as Exhibit 99.1 hereto and is incorporated by reference into this Item 8.01.
