THE UNITED STATES BANKRUPTCY COURT

FOR THE DISTRICT OF DELAWARE

In re:	Chapter 11
QUANERGY SYSTEMS, INC.,1	Case No. 22-11305 (CTG)
Debtor.

NOTES TO MONTHLY OPERATING REPORT

On December 13, 2022 (the “Petition Date”), the above-captioned debtor and debtor in possession (the “Debtor”) filed a voluntary petition for relief under chapter 11 of the Bankruptcy Code with the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”).

Please be advised that the accompanying monthly operating report and the exhibits thereto (the “MOR”) are unaudited, preliminary, and may not comply with generally accepted accounting principles in the United States of America (“U.S. GAAP”) in all material respects.

The MOR is limited in scope, covers a limited time period, and has been prepared solely for the purpose of complying with the reporting requirements of the Bankruptcy Code and the United States Trustee. The unaudited financial statements have been derived from the Debtor’s books and records. The MOR generally reflects the operations and financial position of the Debtor on a consolidated basis with non-Debtor Quanergy Perception Technologies, Inc. The information presented herein has not been subjected to all procedures that would typically be applied to financial information presented in accordance with U.S. GAAP. Upon the application of such procedures, the financial information could be subject to changes, and these changes could be material. The information furnished in the MOR includes normal recurring adjustments, but does not include all of the adjustments that would typically be made for interim financial statements in accordance with U.S. GAAP.

Given the complexity of the Debtor’s business, inadvertent errors, omissions or over-inclusions may have occurred. Accordingly, the Debtor hereby reserves the right to amend or supplement the MOR, if necessary, but shall be under no obligation to do so.

¹  The Debtor and the last four digits of its taxpayer identification number are: Quanergy Systems, Inc. (5845). The Debtor’s mailing address for purposes of the Chapter 11 Case is c/o SierraConstellation Partners, LLC 355 S. Grand Avenue Suite 1450 Los Angeles, CA 90071.
