Item 4.01 Changes in Registrant’s Certifying Accountant.

On January 12, 2026, Crown Electrokinetics Corp. (the “Company”) amicably terminated the engagement of Frank, Rimerman + Co. LLP (“Frank, Rimerman”), the Company’s independent registered public accounting firm. The termination of the engagement of Frank, Rimerman was approved by the Company’s board of directors and audit committee.

Frank, Rimerman did not deliver any reports and has not audited any financial statements of the Company during the period of its engagement and, accordingly, did not issue any adverse opinion or disclaimers of opinion with respect to the Company’s financial statements.

During the term of the Company’s engagement with Frank, Rimerman, there were no disagreements with Frank, Rimerman on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreement(s), if not resolved to the satisfaction of Frank, Rimerman, would have caused it to make reference to the subject matter of the disagreement(s) in connection with its report. During the Company’s two most recent fiscal years and the subsequent interim period through January 12, 2026, there were no reportable events of the type described in Item 304(a)(1)(v) of Regulation S-K.

The Company provided Frank, Rimerman with a copy of the foregoing disclosure and requested Frank, Rimerman to furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether it agrees with the statements made therein. A copy of such letter furnished by Frank, Rimerman is filed as Exhibit 16.1 to this Form 8-K.

On January 12, 2026, the Company’s board of directors and audit committee approved the engagement of CBIZ CPAs P.C. (“CBIZ”) as the Company’s new independent registered public accounting firm.

During the Company’s two most recent fiscal years and the subsequent interim period through January 12, 2026, neither the Company nor anyone on its behalf consulted with CBIZ regarding (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 neither a written report nor oral advice was provided that CBIZ concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue; or (ii) any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and its related instructions) or a reportable event (as described in Item 304(a)(1)(v) of Regulation S-K).
