Change in Certifying Accountants (Form 8-K)

Item 4.01. Changes in Registrant's Certifying Accountant.

(a) Dismissal of Former Independent Registered Public Accounting Firm

On June 30, 2025, Ernexa Therapeutics Inc. (the "Company) dismissed Grant Thornton LLP ("Grant Thornton") as the Company's independent registered public accounting firm effective immediately. The Audit Committee of the Company's Board of Directors (the "Board") approved Grant Thornton's dismissal on June 30, 2025.

Grant Thornton performed audits of the Company's consolidated financial statements for the years ended December 31, 2024 and 2023. Grant Thornton's reports for such years did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles, except that, the reports included an explanatory paragraph describing that substantial doubt was raised as to the Company's ability to continue as a going concern.

During the two years ended December 31, 2024 and the subsequent interim period through June 30, 2025, there were no (i) disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K promulgated by the SEC pursuant to the Securities Exchange Act of 1934, as amended) between the Company and Grant Thornton on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to satisfaction of Grant Thornton, would have caused Grant Thornton to make reference to the subject matter of such disagreements in connection with its report, or (ii) "reportable events," as described in Item 304(a)(1)(v) of Regulation S-K, that would require disclosure under Item 304(a)(1)(v) of Regulation S-K, except for the material weakness in the Company's internal control over financial reporting as of and for the year ended December 31, 2023, stemming from a lack of technical accounting proficiency in complex matters.

The Company furnished Grant Thornton with a copy of the disclosure contained in this Item 4.01 prior to filing this Current Report on Form 8-K with the SEC and requested that Grant Thornton furnish it with a letter addressed to the SEC stating whether or not it agreed with the statements made by the Company in this Item 4.01 insofar as they relate to Grant Thornton's audit services and engagement as the Company's independent registered public accounting firm. Grant Thornton has furnished a letter addressed to the SEC, a copy of which is attached hereto as Exhibit 16.1.

(b) Appointment of New Independent Registered Public Accounting Firm

On July 1, 2025, the Company engaged Haskell & White LLP ("Haskell & White") as the Company's independent registered public accounting firm. The decision to engage Haskell & White was approved by the Audit Committee of the Board.

During the two years ended December 31, 2024 and the subsequent interim period through June 30, 2025, neither the Company nor anyone acting on its behalf has consulted Haskell & White regarding either: (i) 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 financial statements, and no written report or oral advice was provided to the Company by Haskell & White that Haskell & White concluded was an important factor considered by the Company in reaching a decision as to an accounting, auditing or financial reporting issue; or (ii) any matter that was either subject of a disagreement, as that term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K, or a "reportable event," as that term is described in Item 304(a)(1)(v) of Regulation S-K.
