Insights

Auditor change tied to firm combination; disclosures indicate no disputes.

Investar Holding replaced Horne with BDO after Horne’s team joined BDO. This is a structural transition rather than a company-initiated switch. The Audit Committee approved BDO’s appointment on November 3, 2025, maintaining continuity of audit coverage.

Horne’s prior opinions for 2023 and 2024 were clean, and the company reports no disagreements or reportable events through October 31, 2025. The filing also states there were no consultations with BDO prior to engagement. Overall, this reads as a routine auditor realignment, with limited direct impact on financials.

Item 4.01     Changes in Registrant's Certifying Accountant
 
On November 1, 2025, the partners and professional staff of HORNE LLP (“Horne”), which was engaged as the independent registered public accounting firm of the registrant, Investar Holding Corporation (the “Company”), joined BDO USA, P.C. (“BDO”). As a result of this transaction, Horne resigned as the Company’s independent registered public accounting firm on November 1, 2025. On November 3, 2025, following the resignation of Horne, the Company, through and with the approval of its Audit Committee, appointed BDO as its independent registered public accounting firm.
 
The reports of Horne on the financial statements of the Company for the fiscal years ended December 31, 2024 and 2023, did not contain any adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.
 
During the Company’s fiscal years ended December 31, 2024 and 2023, and through October 31, 2025, there were no disagreements between the Company and Horne 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 Horne, would have caused Horne to make reference to the subject matter of the disagreements in connection with its audit reports on the Company’s financial statements. During the Company’s past fiscal years ended December 31, 2024 and 2023, and the interim period through October 31, 2025, Horne did not advise the Company of any of the matters specified in Item 304(a)(1)(v) of Regulation S-K.
 
The Company provided Horne with a copy of this report on Form 8-K in accordance with Item 304(a) of Regulation S-K prior to its filing with the Securities and Exchange Commission (the “SEC”) and requested that Horne furnish the Company with a letter addressed to the SEC stating whether it agrees with the above statements and, if it does not agree, the respects in which it does not agree. A copy of the letter from Horne is filed as Exhibit 16.1 hereto.
 
During the Company’s two most recently completed fiscal years and through the date of engagement of BDO, neither the Company nor anyone on behalf of the Company consulted with BDO regarding (a) 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 as to which the Company received a written report or oral advice that was an important factor in reaching a decision on any accounting, auditing or financial reporting issue; or (b) any matter that was the subject of a disagreement or a reportable event as defined in Items 304(a)(1)(iv) and (v), respectively, of Regulation S-K.
