GLOBAL NOTES AND STATEMENT OF LIMITATIONS,

METHODOLOGY AND DISCLAIMERS REGARDING

APRIL 30, 2024 MONTHLY OPERATING REPORT

The debtor and debtor in possession (the “Debtor”) in the above-captioned chapter 11 case (the “Chapter 11 Case”) has prepared and filed the attached April 30, 2024 Monthly Operating Report (the “MOR”) in the United States Bankruptcy Court for the District of Delaware (the “Court”). The Debtor has prepared the MOR with the assistance of its advisors and professionals solely for the purpose of complying with the reporting requirements applicable in the Chapter 11 Case and is in a format consistent with the instructions provided by the Office of the United States Trustee for the District of Delaware. The financial information contained herein is unaudited, limited in scope, and is not prepared in accordance with accounting principles generally accepted in the United States of America nor in accordance with federal or state securities laws or other applicable non-bankruptcy law or in lieu of complying with any periodic reporting requirements thereunder.

In preparing the MOR, the Debtor relied on financial data available from the limited books and records available to it at the time of such preparation, as well as certain filings from the docket in the Chapter 11 Case. Although the Debtor made commercially reasonable efforts to ensure the accuracy and completeness of the MOR, inadvertent errors or omissions may exist.² For the avoidance of doubt, the Debtor hereby reserves its right to amend and supplement the MOR as may be necessary or appropriate.

Each signatory to the MOR has necessarily relied upon the efforts, statements, advice, and representations of personnel of the Debtor and its advisors and professionals. Each signatory has not (and could not have) personally verified the accuracy of each such statement, representation, and answer contained in the MOR.

¹	The last four digits of the Debtor’s federal tax identification numbers is 5697. The Debtor’s principal office is located at 3500 S. Dupont Hwy, Dover, Delaware 19901.

²	The Debtor, and its agents, advisors, attorneys, and other professionals, as applicable, do not guarantee or warrant the accuracy or completeness of the data that is provided in the MOR.

Case 22-10995-LSS Doc 1087-1 Filed 05/23/24 Page 2 of 7

Part 1: Cash Receipts and Disbursements. The MOR presents the Debtor’s receipts and disbursements for the period from April 1, 2024 through April 30, 2024.

Part 2: Asset and Liability Status. The amounts identified in Part 2 of the MOR are derived from the Debtor’s unaudited and estimated accrual-based Balance Sheet as of April 30, 2024. Postpetition payables includes accounts payable. Please refer to the notes above for information about presentation and limitations that may exist in the MOR.

Part 3: Assets Sold or Transferred. No such transactions or activities during the period from April 1, 2024 through April 30, 2024.

Part 4: Income Statement (Statement of Operations). This MOR presents the Debtor’s best estimate of its cash-basis Statements of Operations for the period from April 1, 2024 through April 30, 2024. Please refer to the notes above for information about presentation and limitations that may exist in the MOR.

Part 5: Professional Fees and Expenses. The Debtor made approved payments to certain restructuring professionals during the period from April 1, 2024 through April 30, 2024.

Part 6: Postpetition Taxes. The Debtor collects, withholds, and incurs withholding, income, and property taxes, as well as other business and regulatory fees and assessments (collectively, the “Taxes and Fees”). The Debtor remits the Taxes and Fees to various federal, state, and local governments (collectively, the “Authorities”). The Debtor pays the Taxes and Fees to the Authorities on a periodic basis, remitting them monthly, semi-monthly, quarterly, semi-annually, or annually depending on the nature and incurrence of a particular Tax or Fee. On November 15, 2022, the Court entered an order [Docket No. 139] authorizing, but not directing, the Debtor to, among other things, pay Taxes and Fees that arise or accrue in the ordinary course of business on a postpetition basis consistent with prepetition practices. The Debtor believes that it is current with respect to any outstanding, postpetition amounts due.

Exhibit E: Balance Sheet. This MOR presents the Debtor’s best estimates of its accrual-based Balance Sheet at April 30, 2024. Accrued Clinical and MFG, and Other include Debtor Professional Fees incurred but unpaid as of April 30, 2024. Please refer to the notes above for information and limitations that may exist in the MOR.
