GOLUB CAPITAL BDC Inc

The management of Golub Capital BDC, Inc. (“GBDC,” and collectively with its subsidiaries, the “Company,” “we,” “us,” “our” and “Golub Capital BDC”) is responsible for establishing and maintaining adequate internal control over financial reporting. 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.

Golub Capital BDC’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 Golub Capital BDC, 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.

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 could become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures could deteriorate.

Management assessed the effectiveness of Golub Capital BDC’s internal control over financial reporting as of September 30, 2024. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control — Integrated Framework issued in 2013. Based on the assessment, management believes that, as of September 30, 2024, our internal control over financial reporting is effective based on those criteria.

Golub Capital BDC’s independent registered public accounting firm that audited the financial statements has issued an audit report on the effectiveness of our internal control over financial reporting as of September 30, 2024. This report appears on page 128.
