Item 4.01.          Changes in Registrants Certifying Accountant.
On July 15, 2021, Vaxart, Inc. (the “Company”) was notified that OUM & Co. LLP (“OUM”), an independent registered public accounting firm, had combined its practice with that of WithumSmith+Brown, PC (“Withum”) and that the name of the combined practice will be “WithumSmith+Brown.” On July 16, 2021, OUM resigned as the auditors of the Company and the Audit Committee of the Company’s Board of Directors engaged Withum to serve as the Company’s new independent registered public accounting firm.
During the Company’s fiscal years ended December 31, 2020 and 2019, and through the date of this Current Report on Form 8-K, the Company did not consult with Withum regarding any of the matters or reportable events described in Item 304(a)(2)(i) and (ii) of Regulation S-K.
The audit report of OUM on the consolidated financial statements of the Company as of and for the fiscal years ended December 31, 2020 and 2019, 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.
In connection with the audit of the Company’s financial statements for the fiscal years ended December 31, 2020 and 2019, and through the date of this Current Report on Form 8-K, there were (i) no disagreements between the Company and OUM on any matters of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements, if not resolved to the satisfaction of OUM, would have caused OUM to make reference to the subject matter of the disagreement in their report on the Company’s consolidated financial statements for such year or for any reporting period since the Company’s last fiscal year end and (ii) no reportable events within the meaning set forth in item 304(a)(1)(v) of Regulation S-K.
The Company provided OUM with a copy of the disclosures in this Form 8-K and has requested that OUM furnish it with a letter addressed to the U.S. Securities and Exchange Commission stating whether or not OUM agrees with the Company’s statements in this Item 4.01. A copy of the letter dated July 19, 2021, furnished by OUM in response to that request, is filed as Exhibit 16.1 to this Current Report on Form 8-K.
