Evaluation of Our Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to provide reasonable assurance that material information required to be disclosed in our periodic reports filed under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and to provide reasonable assurance that such information is accumulated and communicated to our management, our principal executive officer and our principal financial officer, to allow timely decisions regarding required disclosure. Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act, as amended) as of the end of the period covered by this report. Based upon, and as of the date of, this evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures as of December 31, 2023 are effective and the previously disclosed material weakness has been remediated as described below.

Remediation of Prior Material Weakness

In May 2023, in connection with the preparation of our interim financial statements for the period ended March 31, 2023, we determined that our disclosure controls and procedures were not effective due to a material weakness. The material weakness related to our failure to maintain an effective control environment over the internal control activities to ensure the processing of and reporting of accruals associated with upfront payments and issue fees in licensing agreements were complete, accurate and timely.

As of December 31, 2023, management implemented measures that it believes remediated the identified material weakness. Specifically, controls over the preparation of financial statements have been enhanced, including designing, documenting, and implementing additional reconciliations, analysis and review procedures over accruals associated with upfront payments and issue fees in licensing agreements. Based upon the testing and evaluation of the design and operating effectiveness of the new controls, our Chief Executive Officer and our Chief Financial Officer concluded that the material weakness relating to accruals associated with upfront payments and issue fees in licensing agreements was remediated.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal controls over financial reporting, as such term is defined in Rule 13a-15(f) of the Exchange Act. Our management conducted an assessment of the effectiveness of our internal control over financial reporting based on the criteria set forth in the “Internal Control-Integrated Framework (2013)” issued by the Committee of Sponsoring Organization of the Treadway Commission. Based on this assessment, management concluded that, as of December 31, 2023, our internal control over financial reporting was effective.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

This annual report does not include an attestation report of our registered public accounting firm on internal control over financial reporting. We are currently a non-accelerated filer and are therefore not required to provide an attestation report on our internal control over financial reporting until such time as we are an accelerated filer or large accelerated filer.

Changes in Internal Control over Financial Reporting

We have undertaken remediation actions, as discussed above, to address the material weakness in our internal controls over financial reporting. These remediation actions continued through the year ended December 31, 2023, but have not materially affected our internal control over financial reporting. Except as noted above, there were no other changes in our internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) that occurred during the period to which this report relates that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
