Change in Registrant’s Certifying Accountant. (a) Dismissal of independent registered public accounting firm On April 26, 2023, the Audit Committee (the “Committee”) of the Board of Directors of The LGL Group, Inc. (the “Company”) dismissed RSM US LLP (“RSM”) as the Company’s independent registered public accounting firm, effective immediately in anticipation of the appointment of PKF O’Connor Davies, LLP (“PKF”) as the Company’s new independent registered public accounting firm as discussed below. The decision to change the Company’s independent registered public accounting firm from RSM to PKF was unanimously approved by the Committee. The reports of RSM on the consolidated financial statements of the Company for the fiscal years ended December 31, 2022 and December 31, 2021 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. During the fiscal years ended December 31, 2022 and December 31, 2021, there were no “disagreements” (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) between the Company and RSM on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to RSM’s satisfaction, would have caused RSM to make reference to the subject matter of the disagreements in its reports on the consolidated financial statements for such years. During the fiscal years ended December 31, 2022 and December 31, 2021 and the subsequent interim period through April 26, 2023, there were no reportable events of the type described in Item 304(a)(1)(v) of Regulation S-K. In accordance with Item 304(a)(3) of Regulation S-K, the Company provided RSM with a copy of the disclosures contained in this Item 4.01 of this Form 8-K and requested that RSM furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether it agrees with the statements contained herein. A copy of RSM’s letter, dated April 28, 2023, is filed as Exhibit 16.1 to this Form 8-K. (b) Appointment of independent registered public accounting firm As discussed above, the Committee appointed PKF as the Company’s new independent registered public accounting firm effective as of April 26, 2023. During the Company’s two most recent years ended December 31, 2022 and December 31, 2021, neither the Company nor anyone on its behalf consulted PKF regarding either: (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 was provided to the Company nor oral advice was provided to the Company that PKF 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 or reportable event as defined in Regulation S-K, Item 304(a)(1)(iv) and Item 304(a)(1)(v), respectively. The Audit Committee has authorized RSM to respond fully to all inquiries of PKF. Item 8.01. Other Events. On May 2, 2023, the Company issued a press release (the “Auditor Press Release”) related to its change in auditors. A copy of the Auditor Press Release is attached hereto as Exhibit 99.1 and is incorporated herein by reference. Item 9.01. Financial Statements and Exhibits.
