On August 6, 2018, PLx Pharma Inc. (the “Company”) engaged Marcum LLP (“Marcum”) as its independent registered public accountants. This engagement occurred in connection with the Company’s prior independent public accountants, GBH CPAs, PC (“GBH”) resigning, effective August 6, 2018, as a result of combining its practice with Marcum. The engagement of Marcum has been approved by the Audit Committee of the Company’s Board of Directors.

GBH’s reports on the consolidated financial statements of the Company as of and for the fiscal years ended December 31, 2017 and 2016 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 fiscal years ended December 31, 2017 and 2016 and through August 6, 2018, there were no disagreements with GBH on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which if not resolved to GBH’s satisfaction would have caused it to make reference thereto in connection with its reports on the financial statements for such years.
