Item 4.01Changes in Registrant’s Certifying Accountant.

(a) The Audit Committee of Pioneer Power Solutions, Inc. (the “Company”) decided not to renew the engagement of Richter LLP (“Richter”) and therefore has dismissed Richter as the Company’s independent registered public accounting firm, effective March 18, 2014.

The reports of Richter on the Company’s consolidated financial statements for the two most recent fiscal years, ended December 31, 2013 and December 31, 2012, did not contain an adverse opinion or a disclaimer of opinion, and was not qualified or modified as to uncertainty, audit scope, or accounting principles.

During the two most recent fiscal years, ended December 31, 2013 and December 31, 2012, and through March 18, 2014, there were no disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K) with Richter on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Richter, would have caused Richter to make reference to the subject matter of the disagreements in connection with its reports on the consolidated financial statements for such years. Also during this time, there were no reportable events (as defined in Item 304(a)(1)(v) of Regulation S-K).

The Company provided Richter with a copy of the above disclosures and requested that Richter furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether or not it agrees with the statements made above. A copy of Richter’s letter dated March 18, 2014 is attached as Exhibit 16.1 to this Report.

(b) The Audit Committee of the Company approved the engagement of BDO USA, LLP (“BDO”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2014, effective March 18, 2014. During the fiscal years ended December 31, 2013 and December 31, 2012, and through March 18, 2014, neither the Company nor anyone on its behalf has consulted with BDO with respect to any matters or events discussed in Item 304(a)(2)(i) and (ii) of Regulation S-K.
