This Item 4 includes information concerning the controls and controls evaluation referred to in the certifications of our Chief Executive Officer and Chief Financial Officer required by Rule 13a-14 of the Exchange Act included in this Form 10-Q as Exhibits 31.1 and 31.2.

Evaluation of Disclosure Controls and Procedures

Our management, including our Chief Executive Officer and Chief Financial Officer, evaluated as of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of March 31, 2024 and based on this evaluation, have concluded that, as a result of the material weaknesses in internal control over financial reporting as described below, our disclosure controls and procedures were not effective as of March 31, 2024.

Pursuant to Rule 13a-15(e), the term “disclosure controls and procedures” means controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management, including its Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Material Weaknesses

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

In the course of preparing the audited consolidated financial statements as of and for the year-ended December 31, 2023, our management identified material weaknesses in its internal controls over financial reporting related to a deficiency in the design and operation of our financial accounting and reporting controls.

To help address the material weaknesses, we have strengthened our accounting team with the addition of an experienced Controller and Chief Financial Officer and have identified additional accounting resources that are expected to help to remediate the material weaknesses. We will also continue to review the overall internal control environment as we develop the requisite internal control framework. While we believe these efforts will remediate the material weakness, the material weakness cannot be considered fully remediated until the applicable remedial controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively.

Changes in Internal Control over Financial Reporting

Except for the changes intended to remediate the material weakness described above, there were no changes in our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) during the period ended March 31, 2024 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
