(b) Appointment of New Independent Registered Public Accounting Firm

As previously reported, on April 25, 2022, the Audit Committee (the “Audit Committee”) of the Board of Directors of Pioneer Power Solutions, Inc. (the “Company”) decided not to renew the engagement of BDO USA LLP (“BDO”) and therefore had dismissed BDO as the Company’s independent registered public accounting firm, effective immediately.

On May 9, 2022, the Company entered into an engagement agreement with Marcum LLP (“Marcum”), in which Marcum will serve as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2022. During the fiscal years ended December 31, 2021 and December 31, 2020, and the subsequent interim period through May 9, 2022, neither the Company nor anyone on its behalf has consulted with Marcum regarding (i) the application of accounting principles to any 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 that Marcum concluded 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 either the subject of a “disagreement,” as defined in Item 304(a)(1)(iv) of Regulation S-K, or a “reportable event,” as defined in Item 304(a)(1)(v) of Regulation S-K.
