Explanation of Responses:

1. Since the filing of the Form 4 filed by the Reporting Persons on September 7, 2022, and more than 6 months ago, the managed account to which Caligan (as defined below) serves as a consultant has reduced its holding by 480,000 shares of Common Stock, and accordingly, such shares of Common Stock are no longer included in the total amount of securities beneficially owned that are reported in Column 5.

2. This Form 4 is filed by David Johnson ("Mr. Johnson") and Caligan Partners LP ("Caligan" and together with Mr. Johnson, the "Reporting Persons") with respect to the securities held by (i) Caligan Partners Master Fund LP, a Cayman Islands limited partnership, (ii) an affiliated fund to which Caligan serves as investment manager, (iii) managed accounts to which Caligan serves as investment manager, and (iv) a managed account to which Caligan serves as a consultant. Mr. Johnson is the Managing Partner of Caligan and a Managing Member of Caligan Partners GP LLC, the general partner of Caligan.

Remarks:

The Reporting Persons disclaim beneficial ownership in the securities reported on this Form 4 except to the extent of its or his pecuniary interest, if any, therein, and this report shall not be deemed to be an admission that such Reporting Persons are the beneficial owners of such securities for purposes of Section 16 or for any other purpose. Caligan may be deemed to be a director by deputization of Liquidia Corporation (the "Issuer") by virtue of the fact that Mr. Johnson currently serves on the Issuer's board of directors.
