Evaluation of Effectiveness of Disclosure Controls and Procedures

Our management maintains disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) that are designed to provide reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act is processed, recorded, 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 (our principal executive officer and principal financial officer, respectively), as appropriate, to allow for timely decisions regarding required disclosure.

We evaluated, under the supervision and with the participation of management, including our principal executive and principal financial officers, the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this quarterly report. Based on this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of March 31, 2024.

Changes in Internal Control over Financial Reporting

During the quarter ended March 31, 2024, we completed the first phase of the implementation of a new enterprise resource planning (“ERP”) system for our corporate operations, which included financial accounting and reporting, procurement, and payment functions. As part of the implementation, we designed new internal controls and modified and/or enhanced existing internal controls to align with the new ERP system and business processes. We do not believe this implementation has had or will have a material adverse effect on our internal control over financial reporting. There were no additional changes in our internal control over financial reporting identified in management’s evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act that occurred during the period ended March 31, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
