INFORMATION CONTAINED IN THIS REPORT ON FORM 6-K

Change in the Company’s Certifying Accountant

On May 12, 2022, the Company dismissed Ernst & Young (Hellas) Certified Auditors Accountants S.A. (“EY”) as its independent registered public accounting firm.

The audit reports of EY on the Company’s consolidated financial statements as of and for the fiscal years ended December 31, 2020 and 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 principle.

During the fiscal years ended December 31, 2020 and 2021, and the subsequent interim period from January 1, 2022 through the date of termination, (i) the Company did not have disagreements, as such term is defined in Item 16F(a)(1)(iv) of Form 20-F (and the related instructions thereto), with EY 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 EY, would have caused EY to make reference to the subject matter of the disagreements in connection with its reports on the consolidated financial statements for such years, and (ii) there were no “reportable events” as defined in Item 16F(a)(1)(v) of Form 20-F.

The Company provided EY with a copy of this Form 6-K and requested that EY provide the Company with a letter addressed to the Securities and Exchange Commission stating whether it agrees with the above statements. A copy of EY ’s letter is furnished as Exhibit 16.1 to this Form 6-K.

The Audit Committee of the Board of Directors of the Company (the “Audit Committee”) approved the change in the Company’s accountants, taking into account corporate best practices. On May 23, 2022, the Audit Committee engaged Deloitte Certified Public Accountants S.A. as the Company’s new independent registered public accounting firm, starting with the review of the Company's financial results for the year ending December 31, 2022.

Attached to this report on Form 6-K as Exhibit 99.1 is a copy of the press release of the Company dated May 31, 2022, titled “Seanergy Maritime Holdings Corp. Reports First Quarter 2022 Financial Results and Declares Dividend of $0.025 Per Share.”

This Report on Form 6-K is hereby incorporated by reference into the Company's Registration Statements on Form F-3 (File Nos. 333-257693, 333-253332, 333-238136, 333-237500, 333-221058, 333-166697, 333-169813 and 333-214967).
