PENNANTPARK INVESTMENT CORP

The management of PennantPark Investment Corporation (except where the context suggests otherwise, the terms “we,” “us,” “our” and “PennantPark Investment” refer to PennantPark Investment Corporation and its Subsidiaries) is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f), and for performing an assessment of the effectiveness of internal control over financial reporting as of September 30, 2025. Our internal control system is a process designed to provide reasonable assurance to our management and board of directors regarding the preparation and fair presentation of published financial statements.

PennantPark Investment’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. Our 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 PennantPark Investment, and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.

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

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 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 PennantPark Investment’s internal control over financial reporting as of September 30, 2025. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in 2013 Internal Control—Integrated Framework. Based on such assessment management has determined that, as of September 30, 2025, we do not maintain effective internal control over financial reporting due to the material weakness described below.

A material weakness was identified in the operations of control related to the Company's quarterly review of equity investment valuations with respect to the allocation of value of the portfolio company to the Company’s holdings. Although this material weakness did not result in any material misstatement of our consolidated financial statements for the periods presented, there is a possibility they could lead to a material misstatement of account balances or disclosures. Accordingly, management has concluded that this control deficiency constitutes a material weakness.

Management believes that the financial statements included in this Annual Report on Form 10-K present fairly, in all material respects, the Company’s financial position, results of its operations, changes in net assets and cash flows for the periods presented. We believe that the audited consolidated financial statements included in this Annual Report on Form 10-K are accurate. We have begun the process of, and we are focused on, further enhancing effective internal control measures to improve our internal control over financial reporting and remediate this material weakness. Our internal control remediation efforts include the following:

•

Enhance existing review controls of equity investments related to the allocation of the portfolio company’s enterprise value to the Company’s holdings to ensure allocations are consistent with the relevant and respective source document; and

•

Enhancing policies and procedures to demonstrate commitment to improving our overall control environment.

We believe our planned actions to enhance our processes and controls will address the material weakness, but these actions are subject to ongoing management evaluation, and we will need a period of execution to demonstrate remediation. We are committed to the continuous improvement of our internal control over financial reporting and will continue to diligently review our internal control over financial reporting.

reporting as of September 30, 2025. This report appears on page 64.
