Introduction

This Amendment No. 2 amends and supplements the statement on the Schedule 13D filed with the United States Securities and Exchange Commission (the “SEC”) on January 22, 2020 as amended by Amendment No. 1 thereto filed with the SEC on November 3, 2021 (the “Schedule 13D”), related to the ordinary shares, par value $0.01 per share (the “Ordinary Shares”) of RVL Pharmaceuticals plc, an Irish public limited company (the “Issuer”). Capitalized terms used herein without definition shall have the meanings set forth in the Schedule 13D and, unless amended hereby, all information previously filed remains in effect.

This Amendment No. 2 amends Item 2, Item 4, and Item 5 as set forth below. As set forth below, as a result of the transactions described herein, on October 24, 2023, the Reporting Persons ceased to be beneficial owners of more than five percent of the Ordinary Shares.

Item 2. Identity and Background

An amended and restated Exhibit A, identifying the current executive officers and directors of each Reporting Person, is attached to this Amendment No. 2.

Item 4. Purpose of Transaction

Item 4 is amended to add the following paragraph immediately following the second paragraph:

Item 5.

Item 5 of the Schedule 13D is hereby amended and restated in its entirety as follows:

(a)

The aggregate number and percentage of Ordinary Shares identified pursuant to Item 1 beneficially owned by each Reporting Person is stated in rows eleven and thirteen on the cover pages hereto.

Altchem Limited serves as the manager of Orbit Co-Invest A-1 LLC. As a result, Altchem Limited may be deemed to share beneficial ownership of the Ordinary Shares held by Orbit Co-Invest A-1 LLC.

Voting and disposition decisions with respect to Ordinary Shares beneficially owned by Altchem Limited are made by the foundation council of Harsaul Foundation, a foundation organized in Panama, in its absolute discretion.
