Evaluation of disclosure controls and procedures – The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in its Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms, and that such information is accumulated and communicated to its management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

As of the end of the period covered by this report, September 30, 2025 (“the Evaluation Date”), the Company carried out an evaluation, under the supervision and with the participation of its management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of its disclosure controls and procedures. Based upon this evaluation, which excluded the impact of the acquisition of Pintail, discussed below, the Chief Executive Officer and the Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective at a reasonable assurance level as of the Evaluation Date.

As discussed in the Note titled “Acquisition” of the Notes to Consolidated Financial Statements in Part I – Item 1. “Financial Statements” of this Form 10-Q for the quarter ended September 30, 2025, we completed the acquisition of Pintail during the second quarter. As part of our post-closing integration activities, we have been engaged in the process of assessing the internal controls of Pintail and are continuing to integrate policies, processes, people, technology, and operations for the post-acquisition combined company. As permitted for newly acquired businesses by interpretive guidance issued by the staff of the SEC, management has excluded the internal control over financial reporting of Pintail from the evaluation of the effectiveness of our disclosure controls and procedures as of September 30, 2025. We have reported the operating results of Pintail in our Consolidated Statements of Operations and Statements of Cash Flows from the acquisition date through September 30, 2025. As of September 30, 2025, total assets related to Pintail represented approximately 17% of our total assets, recorded on a preliminary basis as the measurement period for the business

combination remained open as of September 30, 2025. Revenues from Pintail represented approximately 22% of our total consolidated revenues for the three months ended September 30, 2025.

*Changes in internal control over financial reporting –*The Company has successfully completed the mapping of Pintail’s accounts to our existing financial reporting systems. The Company is continuing to review key controls and has implemented controls related to all Pintail financial statement line items and consolidation in order to enable the accurate preparation and timely reporting of their results.

Other than the changes to Pintail controls noted above, there were no changes in the Company’s internal control over financial reporting during the third quarter of 2025 which were identified in connection with management’s evaluation required by paragraph (d) of Rules 13a-15 and 15d-15 under the Exchange Act, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
