Endo International (ENDPQ) 8-K Endo Files Plan of Reorganization to Implement Previously Announced Sale Transaction

Exhibit 99.1

ENDO FILES PLAN OF REORGANIZATION TO IMPLEMENT PREVIOUSLY ANNOUNCED SALE TRANSACTION

Paves the Way for Endo to Successfully Conclude Financial Restructuring in Second Quarter of 2024

DUBLIN, December 19, 2023 – Endo International plc (OTC: ENDPQ) (“Endo” or the “Company”) today announced that it has taken an important step toward concluding its financial restructuring process by filing a proposed Plan of Reorganization (the “Plan”) and related Disclosure Statement with the U.S. Bankruptcy Court for the Southern District of New York (the “Court”). These filings pave the way for Endo to promptly emerge from Chapter 11 with a strengthened balance sheet and to advance its ongoing business transformation.

The Plan is a preferred alternative to the previously announced sale of substantially all the Company’s assets to holders of Endo’s first lien debt (the “Ad Hoc First Lien Group”) under Section 363 of the U.S. Bankruptcy Code, with substantially similar terms: a purchase of substantially all of the Company’s assets via a credit bid of existing first lien debt, the assumption of certain liabilities, and offers of employment to all of Endo’s active team members. This ownership transfer, as previously announced, will result in a significant reduction in outstanding indebtedness relative to Endo’s current capital structure and materially benefit opioid and other litigation-related claimants through the establishment of funded trusts. Endo is working with its stakeholders to finalize the documentation related to the transaction.

In addition to the previously reached settlements, the Plan incorporates the recently announced economic settlement in principle with the U.S. Department of Justice providing for payment of $364.9 million over 10 years, or $200 million if the obligation is paid in full on the Plan effective date, plus up to an additional $100 million if the Company’s EBITDA exceeds the defined baseline during the period 2024 to 2028. This settlement is subject to satisfactory resolution of criminal and civil fraud claims against the Company related to the historical sale and marketing of Opana^® ER, which the Company ceased promoting directly to U.S. healthcare providers in 2016.

“We are pleased to have reached this milestone in our financial restructuring, during which time we’ve made steady progress advancing our strategic priorities,” said Blaise Coleman, Endo’s President and Chief Executive Officer. “The Plan provides a clear path forward for Endo to emerge from this process on stronger financial footing in the second quarter of 2024.”

The Company will seek conditional approval of its Disclosure Statement at a hearing before the Court currently scheduled for January 9, 2024. Assuming Court approval, the Disclosure Statement and Plan will be mailed to Endo’s creditors eligible to vote, and the Court will schedule a hearing to confirm the Plan.

Cautionary Statement Regarding Disclosure Statement and Other Documents

The Company cautions investors and potential investors not to place undue reliance upon the information contained in the Disclosure Statement or any other documents that have been or in the future are filed with the Bankruptcy Court and are not prepared for the purpose of providing the basis for an investment decision relating to any of the securities of the Company. The Disclosure Statement and any other documents that have been or in the future are filed with the Bankruptcy Court are limited in scope, cover a limited time period and are prepared solely for the purpose of complying with the reporting requirements of the Bankruptcy Court. The Disclosure Statement and any other documents that have been or in the future are filed with the Bankruptcy Court are not audited or reviewed by independent accountants, are not prepared in accordance with generally accepted accounting principles, are in a format prescribed by applicable bankruptcy laws or rules and are subject to future adjustment and reconciliation. There can be no assurance that, from the perspective of an investor or potential investor in the Company’s securities, the Disclosure Statement and any other documents that have been or in the future are filed with the Bankruptcy Court are complete. Results and projections set forth in the Disclosure Statement or any other documents that have been or in the future are filed with the Bankruptcy Court should not be viewed as indicative of future results.

Cautionary Information Regarding Trading in the Company’s Securities

The Company continues to face certain risks and uncertainties that have been affecting its business and operations, and these risks and uncertainties may affect the Company’s ability to enter into a sale transaction or pursue an alternative emergence transaction (including the filing of a chapter 11 plan) and could impact the outcome of the Company’s voluntary petitions for relief under chapter 11 of the Bankruptcy Code in the United States Bankruptcy Court for the Southern District of New York (collectively, the “Chapter 11 Filings”). Holders of the Company’s equity securities will likely be entitled to little or no recovery on their investment and recoveries to other stakeholders cannot be determined at this time. The Company cautions that trading in the Company’s securities given the pendency of the Chapter 11 Filings is highly speculative and poses substantial risks. Trading prices for the Company’s securities may bear little or no relationship to the actual value realized, if any, by holders of the Company’s securities in the Chapter 11 Filings. Accordingly, the Company urges extreme caution with respect to existing and future investments in its securities.
