Item 4.01. Changes in Registrant's Certifying Accountant.

(a) Dismissal of Independent Registered Public Accounting Firm.

On June 26, 2025, Anterix Inc. (the “Company”) notified Grant Thornton LLP (“Grant Thornton”) that it was dismissed as the Company’s independent registered public accounting firm, effective immediately. The decision to dismiss Grant Thornton was approved by the Company’s Audit Committee of the Board of Directors.

The audit reports of Grant Thornton for the Company’s consolidated financial statements for each of the two most recent fiscal years ended March 31, 2025 and March 31, 2024 did not contain an adverse opinion or a disclaimer of opinion nor were they qualified or modified as to uncertainty, audit scope, or accounting principles. During the Company’s two most recent fiscal years ended March 31, 2025 and March 31, 2024 (and through the interim period of June 26, 2025), there were no disagreements (within the meaning of Item 304(a)(1)(iv) of Regulation S-K) on any matter of accounting principles or practices, financial statement disclosure, or auditing scope and procedures, which disagreement(s), if not resolved to Grant Thornton’s satisfaction, would have caused it to make reference to the subject matter of the disagreement(s) in connection with its report. During the Company’s fiscal years ended March 31, 2025 and March 31, 2024, there were no reportable events (as that term is defined in Item 304(a)(1)(v) of Regulation S-K).

The Company provided Grant Thornton with a copy of this Current Report on Form 8-K prior to its filing with the Securities and Exchange Commission (“SEC”) and requested that Grant Thornton furnish the Company with a letter addressed to the SEC stating whether or not Grant Thornton agrees with the above statements. A copy of the letter from Grant Thornton addressed to the SEC dated June 30, 2025 is filed with this Current Report on Form 8-K as Exhibit 16.1.

(b) Engagement of New Independent Registered Public Accounting Firm

On June 25, 2025, the Company’s Audit Committee approved the engagement of Deloitte & Touche LLP (“Deloitte”) as the Company’s independent registered public accounting firm for the year ending March 31, 2026, effective immediately, subject to completion of Deloitte’s standard client acceptance procedures and execution of an engagement letter.

During the Company’s two most recent fiscal years ended March 31, 2025 and March 31, 2024, neither the Company, nor anyone acting on its behalf, consulted with Deloitte on: (i) any matter regarding 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 no written report or oral advice was provided to the Company by Deloitte that was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue; or (ii) any matter that was the subject of any disagreement (as described in Item 304(a)(1)(iv) of Regulation S-K and the related instructions thereto) or a reportable event (as defined in Item 304(a)(1)(v) of Regulation S-K).
