Item 4.01 — Changes in Registrant’s Certifying Accountant.
On April 13, 2022, upon the completion of a comprehensive selection process, the Audit Committee (the “Audit Committee”) of the Board of Directors of T-Mobile US, Inc. (the “Company”) dismissed PricewaterhouseCoopers LLP (“PwC”) and engaged Deloitte & Touche LLP (“Deloitte”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2022, subject to Deloitte’s standard client acceptance procedures and execution of an engagement letter. The Company believes the appointment of Deloitte is in the best interest of its shareholders, including from efficiency benefits realized through alignment of our audit firm with that of Deutsche Telekom AG, who selected and approved Deloitte as its auditor on April 7th, 2022 in connection with the European Union’s regulations on auditor rotation requirements. The change will each become effective immediately after the Company files its Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2022 with the U.S. Securities and Exchange Commission (“SEC”).
PwC’s reports on the Company’s consolidated financial statements and the effectiveness of internal control over financial reporting, which were included in the Company’s Annual Reports on Form 10-K for the fiscal years ended December 31, 2021 and 2020, did not contain an adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.
During the fiscal years ended December 31, 2021 and 2020, and the subsequent interim period through April 13, 2022, there were: (i) no disagreements within the meaning of Item 304(a)(1)(iv) of Regulation S-K between the Company and PwC on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to PwC’s satisfaction, would have caused PwC to make reference thereto in PwC’s reports; and (ii) no “reportable events” within the meaning of Item 304(a)(1)(v) of Regulation S-K.
The Company provided PwC with a copy of the foregoing disclosures and requested that PwC furnish a letter addressed to the U.S. Securities and Exchange Commission stating whether or not it agrees with the foregoing disclosures. A copy of PwC’s letter, dated April 15, 2022, is filed as Exhibit 16.1 hereto.
During the fiscal years ended December 31, 2021 and 2020, and the subsequent interim period through April 13, 2022, neither the Company nor anyone on its behalf has consulted with Deloitte regarding: (i) the application of accounting principles to a specific 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 to the Company that Deloitte concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing, or financial reporting issue; (ii) any matter that was the subject of a disagreement within the meaning of Item 304(a)(1)(iv) of Regulation S-K; or (iii) any “reportable event” within the meaning of Item 304(a)(1)(v) of Regulation S-K.
