Item 4.01 Changes in Registrant’s Certifying Accountant.

On June 23, 2026, the audit committee (the “Audit Committee”) of the board of directors (the “Board”) of CDT Equity Inc. (the “Company”) (i) approved the dismissal of CBIZ CPAs P.C. (“CBIZ CPAs”) as the Company’s independent registered public accounting firm and (ii) approved the engagement of Carr, Riggs & Ingram, L.L.C. (“CRI”) as the Company’s independent registered public accounting firm.

CBIZ CPAs’ audit report on the Company’s consolidated financial statements as of and for the year ended December 31, 2025 did not contain any adverse opinion or disclaimer of opinion, nor was it qualified or modified as to uncertainty, audit scope, or accounting principles, except that the audit report on the consolidated financial statements of the Company for the year ended December 31, 2025 contained an explanatory paragraph regarding the Company stating that there was substantial doubt about the Company’s ability to continue as a going concern. As previously disclosed in the Company’s current report on Form 8-K filed on April 25, 2025, on April 24, 2025 Marcum LLP was dismissed, and on April 25, 2025 CBIZ CPAs was appointed, as the Company’s independent registered public accounting firm.

From the period starting April 25, 2025 through June 23, 2026, there were (i) no disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) between the Company and CBIZ CPAs on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of CBIZ CPAs, would have caused CBIZ CPAs to make reference to the subject matter of the disagreements in connection with its reports on the consolidated financial statements for the year ended December 31, 2025, and (ii) no “reportable events” (as defined in Item 304(a)(1)(v) of Regulation S-K and the related instructions), except for the material weaknesses in the Company’s internal control over financial reporting related to: (i) the segregation of duties is limited and heavily reliant on interim personnel and third-party consultants to perform these activities, (ii) the Company lacks a formal process for review and approval of significant transactions and accounts on a contemporaneous basis and there have been numerous, recurring errors in account balances and disclosures, (iii) the Company has not designed adequate and appropriate internal controls under an appropriate internal control over financial reporting framework, (iv) the Company did not appropriately review and evaluate the accounting implications of all material transactions that occurred in the audit period which resulted in a restatement of previous periods, and (v) the review controls around certain related party transactions did not operate consistently and the review of such transactions was not always contemporaneously documented, each as disclosed in the Company’s Annual Report for the fiscal year ended December 31, 2025.

During the Company’s two most recent fiscal years ended December 31, 2025 and 2024 and the subsequent period prior to the engagement of CRI on June 23, 2026, neither the Company nor anyone on its behalf has consulted with CRI on either (a) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s consolidated financial statements, and neither a written report nor oral advice was provided to the Company by CRI that CRI concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue, or (b) any matter that was the subject of a disagreement, as that term is defined in Item 304(a)(1)(iv) of Regulation S-K, or a reportable event as set forth in Item 304(a)(1)(iv) of Regulation S-K.

The Company provided CBIZ CPAs with a copy of this Current Report on Form 8-K prior to its filing with the U.S. Securities and Exchange Commission (the “SEC”) and requested that CBIZ CPAs furnish the Company with a letter addressed to the SEC stating whether it agrees with the above statements made by the Company in response to Item 304(a) of Regulation S-K and, if it does not agree, the respects in which it does not agree. A copy of CBIZ CPAs’ letter, dated June 29, 2026, is filed as Exhibit 16.1 (which is incorporated by reference herein) to this Current Report on Form 8-K.
