Remediation

As disclosed in Part II, Item 9A of the Company's Annual Report on Form 10–K for the yer ended December 31, 2022, during the first quarter of 2023 management identified material weaknesses with respect to insufficient controls over the reporting, classification, and disclosure of loans, investments and individual cash flow line items and lack of sufficient controls around the financial reporting process to allow for the timely release of financial statements.

Throughout the year ended December 31, 2023, management implemented its previously disclosed remediation plan to update its design and implementation of controls to remediate the aforementioned deficiencies and enhance the Company's internal control environment, which included:

•Hiring additional resources within our accounting and finance department for financial statement preparation and review and providing additional training to implement and monitor our policies and procedures;

•Enhancing controls with additional procedures for the preparation of financial statement disclosures including the design and implementation of new financial preparation tools to allow more detailed review and documentation for review and procedures relating to the reporting, classification and disclosure of loans, investments and individual cash flow line items in the Company’s financial statements and the calculation of public float for purposes of determining SEC filing deadlines; and

•Developing enhanced documentation and review procedures for financial statement preparation and disclosures, including enhancing the financial statement review process by including additional steps in the review process with respect to the reporting, classification and disclosure of loans, investments and individual cash flow line items in its financial statements and the calculation of the Company’s public float for purposes of determining SEC filing deadlines.

Horizon’s management completed testing of the implemented controls during the quarter ended December 31, 2023, and found such controls to be operating effectively. As a result, management has concluded that the foregoing material weaknesses in internal control over financial reporting have been remediated as of December 31, 2023.
