Horizon Technology Finance Corp

Management of Horizon Technology Finance Corporation (the “Company”) is responsible for establishing and maintaining adequate internal control over the Company’s financial reporting. The Company’s internal control system is a process designed to provide reasonable assurance to management and the board of directors regarding the preparation and fair presentation of published financial statements.

The Company’s internal control over financial reporting includes policies and procedures that pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions recorded necessary to permit the preparation of financial statements in accordance with U.S. generally accepted accounting principles. The Company’s policies and procedures also provide reasonable assurance that receipts and expenditures are being made only in accordance with authorizations of management and the directors of the Company, and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the Company’s financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness as to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2025. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission inInternal Control —* Integrated Framework* issued in 2013. Based on the assessment, management believes that, as of December 31, 2025, the Company’s internal control over financial reporting is effective based on those criteria.

The Company’s independent registered public accounting firm that audited the financial statements has issued an audit report on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2025, which appears in this annual report on Form 10-K.
