HORNBECK OFFSHORE SERVICES, INC.

Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.

Changes in Internal Control Over Financial Reporting

Except as described below, there were no changes in our internal control over financial reporting during the three months ended September 30, 2026 that have materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Upon closing of the Merger on September 1, 2026, there was a change in management and the historical consolidated financial statements of Legacy Hornbeck became the historical consolidated financial statements of the registrant. Furthermore, for the period following the Merger, the Company’s internal control over financial reporting was comprised of both Legacy Hornbeck and Legacy Helix systems, processes and controls. These changes materially affected the Company's internal control over financial reporting during the quarter ended September 30, 2026.

During the quarter ended September 30, 2026, we implemented additional closing procedures to enable our financial reporting process and initiated plans to begin integrating Legacy Hornbeck and Legacy Helix systems, processes and controls. Once integrated, we expect certain of these changes to have a significant impact on internal control over financial reporting going forward, primarily related to control ownership and the modification of inputs, processes and software platforms. We will continue to monitor and upgrade our internal controls, as necessary or appropriate for our business post-Merger, but cannot assure you that such actions will be sufficient to provide us with effective internal control over financial reporting.
