EXPLANATORY NOTE

CID HoldCo, Inc. (the “Company”) is filing this Amendment No. 1 (this “Amendment”) to its Quarterly Report on Form 10-Q for the quarter ended June 30, 2026 that was filed with the U.S. Securities and Exchange Commission on September 25, 2026 (the “Original Report”) solely to correct the cover page check box erroneously indicating that the Company had not filed all reports required to be filed during the preceding 12 months. This Amendment contains only the cover page, this explanatory note, the exhibit index, the signature page and the new certifications (as further explained in the last paragraph of this explanatory note). Except for the foregoing, no other changes have been made to the Original Report, and this Amendment does not amend, update, or modify any other part of the Original Report, including the financial statements or disclosures therein. The Original Report continues to speak as of the date of the Original Report, and the Company has not updated the disclosures contained therein to reflect any events that have occurred as of a date subsequent to the date of the Original Report. Accordingly, this Amendment should be read in conjunction with the Original Report.

As required by Rule 12b-15 of the Securities Exchange Act of 1934, as amended, this Amendment contains new certifications by the Company’s principal executive officer and principal financial officer under Section 302 of the Sarbanes-Oxley Act of 2002, which are being filed as exhibits to this Form 10-Q/A. As no financial statements are included in this Amendment nor does this Amendment contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, the Company is not including paragraphs 3, 4 or 5 of the certifications by the Company’s principal executive officer and principal financial officer under Section 302 of the Sarbanes-Oxley Act of 2002 in Exhibits 31.3 and 31.4. As no financial statements are included in this Amendment, this Amendment does not contain certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002.

Item 6. Exhibits

The following exhibits are filed as part of, or incorporated by reference into, this Quarterly Report on Form 10-Q.
