Explanatory Note

Pursuant to Rule 13d-2 of the Securities Exchange Act of 1934, as amended, this Amendment No. 1 (“Amendment No. 1”) amends certain items of the Schedule 13D filed with the Securities and Exchange Commission (the “SEC”) on September 5, 2023 (the “Schedule 13D”) relating to the ordinary shares, nominal value $0.01 per share (as defined in the Schedule 13D, the “Ordinary Shares”), of RVL Pharmaceuticals plc, an Irish public limited company (as defined in the Schedule 13D, the “Issuer”), which are beneficially owned by Athyrium Opportunities IV Acquisition 2 LP (“Acquisition Fund”), Athyrium Opportunities Associates IV LP (“Associates IV LP”), Athyrium Opportunities Associates IV GP LLC (“Associates IV GP”), Athyrium Opportunities IV Co-Invest 2 LP (“Co-Invest 2 LP”), Athyrium Opportunities Associates IV Co-Invest LLC (“Co-Invest LLC”), Athyrium Funds GP Holdings LLC (“Funds GP Holdings”) and Jeffrey A. Ferrell (“Mr. Ferrell,” and collectively, the “Reporting Persons”). This Amendment No. 1 amends the Schedule 13D on behalf of the Reporting Persons to furnish the information set forth herein. Except as set forth below, all Items of the Schedule 13D remain unchanged. All capitalized terms contained herein but not otherwise defined shall have the meanings ascribed to such terms in the Schedule 13D.

Item 4. Purpose of Transaction

Item 4 of the Schedule 13D is hereby amended and supplemented as follows:

Voluntary Petition for Bankruptcy

On October 12, 2023 (the “Petition Date”), RevitaLid Pharmaceutical Corp., RVL Pharmaceuticals, Inc. and RVL Pharmacy, LLC (the “Debtors”), each an indirect subsidiary of the Issuer, filed voluntary petitions (Case No. 23-11704 (BLS)) (the “Chapter 11 Cases”) for relief under Chapter 11 of title 11 of the United States Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”). The Issuer and its subsidiaries other than the Debtors were not included in the Chapter 11 Cases. The petitions were part of the Debtors’ agreement with its sole secured lender, funds managed by Athyrium Capital Management, L.P. (“Athyrium”), and other key stakeholders, to effectuate a change of control transaction through prepackaged bankruptcy cases commenced in the United States Bankruptcy Court for the District of Delaware today. Athyrium is an investment adviser that is registered with the SEC. It advises certain private funds that invest through Acquisition Fund and Co-Invest 2 LP. Mr. Ferrell is one of the principal owners of Athyrium and is also the managing member of Funds GP Holdings.

The Debtors have sought approval of a variety of “first day” motions containing customary relief intended to enable the Debtors to continue ordinary course operations during the Chapter 11 Cases. The Debtors continue to operate their businesses as a “debtor-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. The Issuer is expected to commence a wind-down of any remaining operations of the Issuer and its subsidiaries other than the Debtors. All of the Issuer’s outstanding Ordinary Shares, are expected to be cancelled upon completion of its wind-down, anticipated to be completed during the year ended December 31, 2024, likely resulting in no recovery to any holders of Ordinary Shares.

Prepackaged Plan of Reorganization

On the Petition Date, the Debtors also filed with the Bankruptcy Court a pre-packaged chapter 11 plan of reorganization (as amended, restated, supplemented or otherwise modified from time to time, the “Plan”). The Plan contemplates, among other things, that funds managed by Athyrium will exchange their outstanding debt into equity of a newly-created entity (“NewCo”) at emergence, which will either (1) directly hold 100% of the equity interests of RevitaLid Pharmaceutical Corp., which is currently an indirect wholly owned subsidiary of the Issuer, or (2) indirectly hold 100% of the equity interests of RVL Pharmaceuticals, Inc., which is currently a wholly owned subsidiary of RevitaLid Pharmaceutical Corp. and the direct parent of RVL Pharmacy, LLC. Funds managed by Athyrium will receive 97.5% of the equity in NewCo, and holders of the SPA Rejection Unsecured Claims (as defined in and pursuant to the Plan) will receive their pro rata share of the remaining 2.5% of the equity in NewCo, subject to dilution by the Management Incentive Plan (as defined in the Plan) and future investments.


CUSIP No. G6S41R101		SCHEDULE 13D/A

The foregoing description of the Plan does not purport to be complete and is qualified in its entirety by reference to the full text of the Plan, which is attached as Exhibit 7.7 hereto and is incorporated herein by reference.

DIP Financing Agreement

Subject to the Bankruptcy Court’s entry of an interim order approving debtor-in-possession financing, the Debtors and one or more funds managed by Athyrium, as lenders (collectively, the “DIP Lenders”) have agreed to enter into a senior secured super-priority debtor-in-possession credit facility (the “DIP Facility”) in a maximum principal loan amount of $17.5 million, subject in all respects to the terms and conditions set forth in the interim order and the underlying loan agreement (the “DIP Financing Agreement”). Pursuant to the DIP Financing Agreement, the DIP Facility consists of multi-draw term loans with up to $7.5 million to be made available upon the Bankruptcy Court’s entry of an order approving the DIP Facility on an interim basis. The DIP Financing Agreement has various customary covenants, as well as covenants mandating compliance by the Debtors with a 7-week approved budget updated every two weeks and maintenance of minimum liquidity of $2.5 million. The proceeds of all or a portion of the proposed DIP Facility may be used solely in accordance with the approved budget, among other things, for post-petition general working capital for the Debtors, payment of fees and expenses in connection with the DIP Facility and payment of professional fees and other charges and expenses in connection with the Chapter 11 Cases.

Item 7. Material to be Filed as Exhibits.

Item 7 of the Schedule 13D is hereby amended and supplemented by adding the following:

7.7	Debtors’ Joint Prepackaged Plan of Reorganization Pursuant to Chapter 11 of the Bankruptcy Code (incorporated by reference to Exhibit 99.1 to the Issuer’s Current Report on Form 8-K filed on October 13, 2023).
