(f/k/a Helix Energy Solutions Group, Inc.), a Delaware corporation (the “Company”), completed its business combination with legacy Hornbeck Offshore Services, Inc., a Delaware corporation (“Legacy Hornbeck”), pursuant to that certain Agreement and Plan of Merger, dated as of April 22, 2026, by and among Helix Energy Solutions Group, Inc., a Minnesota corporation (prior to the completion of the Conversion (as defined below), Merger (as defined below) and name change (as discussed below), “Helix”), Legacy Hornbeck, Odyssey Sub, Inc., a Delaware corporation and direct, wholly owned subsidiary of Helix, and Hercules Sub LLC, a Delaware limited liability company and direct, wholly owned subsidiary of Helix (the “Merger”). In connection with the completion of the Merger, Helix converted from a Minnesota corporation to a Delaware corporation (the “Conversion”) and changed its name from “Helix Energy Solutions Group, Inc.” to “Hornbeck Offshore Services, Inc.”
Item 4.01
Changes in Registrant’s Certifying Accountant.
(a) Dismissal of Independent Registered Public Accounting Firm
KPMG LLP (“KPMG”) served as the independent registered public accounting firm of Helix prior to completion of the Merger. On September 2, 2026, the audit committee (the “Audit Committee”) of the Company’s board of directors approved the dismissal of KPMG as the Company’s independent registered public accounting firm, effective as of September 2, 2026.
KPMG’s audit reports on Helix’s consolidated financial statements as of and for the years ended December 31, 2025 and 2024 did not contain an adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.
During the fiscal years ended December 31, 2025 and 2024 and the subsequent interim period through September 2, 2026, (i) there were no disagreements within the meaning of Item 304(a)(1)(iv) of Regulation S-K with KPMG on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, any of which that, if not resolved to KPMG’s satisfaction, would have caused KPMG to make reference to the subject matter of any such disagreement in connection with its reports for such years and interim period, and (ii) there were no reportable events within the meaning of Item 304(a)(1)(v) of Regulation S-K.
The Company provided KPMG with a copy of the above disclosures and requested that KPMG furnish it with a letter addressed to the U.S. Securities and Exchange Commission stating whether KPMG agrees with the statements made herein. A copy of KPMG’s letter dated September 2, 2026 is filed as Exhibit 16.1 to this Current Report on Form 8-K.
(b) Appointment of the Incoming Independent Registered Public Accounting Firm
On September 2, 2026, the Audit Committee approved the engagement of Ernst & Young LLP (“EY”) as the Company’s independent registered public accounting firm.
During the fiscal years ended December 31, 2025 and 2024 and the subsequent interim period through September 2, 2026, neither the Company nor anyone on the Company’s behalf consulted with EY regarding (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 no written report or oral advice was provided to the Company by EY that EY concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue; or (ii) any matter that was either the subject of a disagreement, as that term is described in Item 304(a)(1)(iv) of Regulation S-K, or a reportable event, as that term is defined in Item 304(a)(1)(v) of Regulation S-K.

Ladies and Gentlemen:
We were
previously principal accountants for Helix Energy Solutions Group, Inc. and, under the date of February 26, 2026, except for the effects of the discontinued operations as discussed in Note 4, as to which the date is August 11, 2026, we
