Amendment Description This Amendment No. 1 to the Quarterly Report on Form 10-Q (the “Form 10-Q/A”) of Hall Chadwick Acquisition Corp. for the quarterly period ended June 30, 2026, is being filed to replace the financial statements, and any related revisions necessary to reflect those corrected financial statements, included in the original Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission.   Following the filing of the original Form 10-Q, the management determined that an incorrect version of the financial statements had been filed. Accordingly, this Form 10-Q/A amends and replaces the previously filed financial statements with the correct version.   The required changes include the following major amendments to the balance sheet:   i.Correction to APIC to zero and transfer the excess to accumulated deficit, resulting in a reduction of the APIC balance by $7,433,993.   ii.Adjustment of the carrying value of Class A ordinary shares subject to possible redemption under the Commitments and Contingencies section to applicable redemption value (trust account balance) as at June 30, 2026 and December 31, 2025.   Management has completed its evaluation under ASC 250, Accounting Changes and Error Corrections and determined that the affected financial statements should be revised as a little r revision. This conclusion has been drawn as the errors were not material to the previously issued financial statements. The nature and effects of the revisions are further described in Note 2, “Revision of Previously Issued Financial Statements.”   The Company emphasizes that the inclusion of the incorrect financial statements in the original filing was unintentional and was not the result of any attempt to misstate or misrepresent the Company’s financial condition or results of operations. Except for the replacement of the financial statements, and any related revisions that were identified during review or necessary to reflect those corrected financial statements, no other changes have been made to the original Form 10-Q. All other disclosures contained in the original filing remain unchanged and continue to be accurate as of the date of the original filing.   This Form 10-Q/A should be read in conjunction with the original Form 10-Q filed for the quarterly period ended June 30, 2026.   Pursuant to Rule 12b-15 under the Securities Exchange Act of 1934, as amended, this Form 10-Q/A also contains new certifications by the Company’s principal executive officer and principal financial officer, filed as exhibits hereto.
